Hello!

Description:
NetBeans doesn't work by default if (only) jdk8-openjdk is installed. I installed jdk8-openjdk and removed jdk7-openjdk as instructed by the wiki and used the script archlinux-java to switch the Java-Environment, as well as the fix option. During startup NetBeans complains about the missing JDK (see attached screenshot). Furthermore the JVM complains about the usage of memory-options through NetBeans which are not unsupported.

$ netbeans
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=384m; support was removed in 8.0
OpenJDK 64-Bit Server VM warning: ignoring option PermSize=32m; support was removed in 8.0

Workaround:
Use NetBeans with the option "--jdkhome" and the parameter "/usr/lib/jvm/java-default-runtime" or "/usr/lib/jvm/java-8-openjdk"
Alternative:
Edit the global netbeans.conf file stored under /usr/share/netbeans/etc/netbeans.conf and add the line:
netbeans_jdkhome="/usr/lib/jvm/java-default-runtime" or
netbeans_jdkhome="/usr/lib/jvm/java-8-openjdk"

Possible cause:
As far as I know /usr/bin/netbeans should detect and use the correct JDK and is also responsible for the memory-options which should not applied anymore.

Additional info:
* package version: netbeans 8.0-1
* see attached screenshot (clean test user)


Steps to reproduce:
1. Install jdk8-openjdk
2. If installed: remove jdk7-openjdk
3. Set java-environment with archlinux-java
4. Execute netbeans

Confirmed here too. It occurs with OpenJdk 7 as well.
Comment by Guillaume ALAUX (galaux) - Monday, 18 August 2014, 16:14 GMT
Just for the record, I had this issue and cannot reproduce it now that I have removed my ~/.netbeans directory.

Could you please provide output of the following:

$ grep -ir home ~/.netbeans

As explained in this thread [0], could you please (first backup then) remove your ~/.netbeans directory

You're changing your comment to fast!

1. Adding
netbeans_jdkhome="{$JAVA_HOME}"
doesn't work.

2. You mentioned the lack of JDK-8-Support in NetBeans, but the referenced WIKI-Page was last edited in 2013


3. Attached grep -ir home ~/.netbeans
3.1 Installed both JDK7 and JDK8
3.2 Deleted ~/.netbeans
3.3 Execute netbeans
3.4 Activate JavaSE-Plugin (preinstalled)
3.5 Exit NetBeans

Yes I don't know what went on with my comments here: I see my old one. Anyway.

1. What about adding directly:
netbeans_jdkhome="/usr/lib/jvm/java-default-runtime"

2. What do you mean?
Comment by Peter Weber (hoschi) - Tuesday, 19 August 2014, 08:39 GMT
I've also edited my post above you. But now let us keep linear ;-)

1. That works, I've already done that before (see original report)
2. See edit above

> 1. That works, I've already done that before (see original report)
Oh right, my bad.
@xyproto: then I guess you can go ahead and add the following to /usr/share/netbeans/etc/netbeans.conf :
netbeans_jdkhome="/usr/lib/jvm/java-default-runtime"

2. Ok. I will let Xyproto see about that.

3. File is empty. Nevermind, it turns out we do not need it.

So my old comment that actually disappeared was about /usr/share/netbeans/platform/lib/nbexec that (in our case) is passed an empty "--jdkhome". This makes this script try to manually guess where the JVM is installed. It fails in doing so without even trying to see what JAVA_HOME is set to.
Here is a bug report about that opened in 2013 (though different use case)
https://netbeans.org/bugzilla/show_bug.cgi?id=235954
I will see if upstream would consider a patch for this. In the meantime I think setting netbeans_jdkhome as previously stated is a good solution.

Sorry for the empty file, I've attached it now.
I will add a comment on the wiki for this issue in the meantime today afternoon (CEST).

Thank you

Question:
Shouldn't we provide an already modified "/usr/share/netbeans/etc/netbeans.conf" with "netbeans_jdkhome="/usr/lib/jvm/java-default-runtime"", as this modification is now mandatory?
Comment by Guillaume ALAUX (galaux) - Thursday, 21 August 2014, 10:40 GMT
That's what I am suggesting yes.
Comment by Alexander F. Rødseth (xyproto) - Sunday, 24 August 2014, 11:07 GMT
Hi, thanks for reporting this. I will look into the problem and most likely change netbeans_jdkhome in netbeans.conf, as suggested.
Comment by Alexander F. Rødseth (xyproto) - Sunday, 24 August 2014, 16:57 GMT
Netbeans has updated the available download for version 8.0.
After following the steps to reproduce, it worked perfectly fine here.
Updating the netbeans package to "netbeans-8.0-2" (internal netbeans version 201403101706).

Please check if it is working correctly and report back. Thanks.

I've updated with pacman to netbeans-8.0-2 but I still need the workaround in the netbeans.conf.

As with previous version: netbeans starts fine here. Still, /usr/share/netbeans/platform/lib/nbexec has the wrong $jdkhome. I can see the issue when trying to activate "java web and EE" plugin.
Comment by Alexander F. Rødseth (xyproto) - Wednesday, 27 August 2014, 18:31 GMT
Got you. Will update the package to include the workaround as well.
Comment by Peter Weber (hoschi) - Wednesday, 03 September 2014, 11:28 GMT
I switched jdkhome now to "/usr/lib/jvm/default", looks like this is now the correct link? The old one still works.
Comment by Guillaume ALAUX (galaux) - Wednesday, 03 September 2014, 12:12 GMT
True. Last "java-common" provides link "default" to a valid JVM and link "default-runtime" to a valid JRE. This was required by software (IcedTea-web for instance). The old link "java-default-runtime" still points at "default" (I plan on keeping it for a couple of weeks) but from now on we should rely on "default".

@xyproto: you will need to use
netbeans_jdkhome="/usr/lib/jvm/default" in /usr/share/netbeans/etc/netbeans.conf
Comment by Tomasz Kołodziejski (neo) - Sunday, 07 September 2014, 17:51 GMT
In my case I had to set:
netbeans_jdkhome="/usr/lib/jvm/java-7-openjdk"

Setting it just "/usr/lib/jvm/default" did not work.
Comment by Guillaume ALAUX (galaux) - Monday, 08 September 2014, 19:27 GMT
Well then I guess this is an issue with your /usr/lib/jvm/default not pointing at the right JDK. Anyway, with no log nor error message no one can say!
Comment by Tomasz Kołodziejski (neo) - Tuesday, 09 September 2014, 03:34 GMT
I'm sorry. It's netbeans_jdkhome="/usr/lib/jvm/java-default-runtime" that didn't work. It was suggested on wiki (https://wiki.archlinux.org/index.php/netbeans)
Comment by Guillaume ALAUX (galaux) - Tuesday, 09 September 2014, 07:55 GMT
Ok. This is now fixed: wiki now says "/usr/lib/jvm/default"
Comment by Guillaume ALAUX (galaux) - Tuesday, 09 September 2014, 07:59 GMT
@xyproto: netbeans-8.0-2 still ships netbeans.conf with jdkhome commented out. Is there any reason to hold this fix?
Comment by Alexander F. Rødseth (xyproto) - Wednesday, 10 September 2014, 09:47 GMT
No other reason than unusually busy weeks and traveling for a wedding this weekend. Looking at it now.
Comment by Alexander F. Rødseth (xyproto) - Wednesday, 10 September 2014, 10:17 GMT
Fixed. The updated package will appear in [community] shortly.
Comment by Guillaume ALAUX (galaux) - Sunday, 12 October 2014, 20:58 GMT
@Xyproto: the issue for this bug came from package "java-common". Its replacements now do not use the "java wrapper" script that induced this error. I have checked and you could safely get rid of the "netbeans_jdkhome" line here:

Thanks for testing.

I removed the config line for the latest release of the netbeans package. Closing this one.
