Is this still happening? Can you try an earlier openjdk version (17 or 11)? Java has seen some updates recently so maybe the problem is resolved? Please let us know.

I have two computers or better my private PC and an Arch VM at work.
Both have installed the same versions (ghidra + jdk).
It does not work in the VM (but has in the past), but works on my PC.

but I will try if I find some time at work...

It tried jdk17 + jdk11
--> as expected with no difference (why there should be any if it works with jdk18 on on PC and doesn't on another?)

I addes 2 files I generated with strace while jdk 11 was set globally
strace ghidra > ghidra_strace.txt 2>&1
strace ghidra -f > ghidra_strace_subprocesses.txt 2>&1

You can see the error in the first file and also that jdk 11 is used in the second one...

sorry: i used strace -ff in the second run, not -f

OK, the system is not accepting my file... even if they are now all smaller than 2M... giving up
Comment by Danny Schneider (schnedan) - Monday, 08 August 2022, 06:57 GMT
if you want the files, provide an Mailadress please

There are no other reports about this, so if it works on your PC but not the VM, it's fairly safe to assume there is something mysterious about the VM it doesn't like. Seeing as there is no identifiable or actionable bug here (yet), probably best at this stage if you take it to the support channels (forum/IRC/etc) where others might be able to assist.
