Description:
since a recent "pacman -Syu" I noticed that the "internal web browser" is disabled in eclipse's options ( window -> preferences -> general -> web browser ),
the option "internal web browser" is greyed out in the GUI,

this bug occurs only if the user selects the GTK2 GUI, by setting this 2 lines before the line "--launcher.appendVmargs" in file /usr/lib/eclipse/eclipse.ini :

--launcher.GTK_version
2

3 days ago the "internal web browser" was available even if the user chooses GTK2 GUI in eclipse, the bug has occured since a recent system update ( pacman -Syu ), during this update webkit2gtk package was updated, and also some others packages related to webkit, maybe it's the root cause of this bug,

I use JEE perspective in eclipse ( for tomcat server ),
the bug doesn't occur if GTK3 GUI mode is used in eclipse, something seems broken between webkit and GTK2,

I use plasma 5 ( kde )


Additional info:
* package version(s) eclipse-common 4.7.1.a-1, eclipse-java 4.7.1.a-1

* config and/or log files etc.


Steps to reproduce:
- set eclipse in "GTK2 mode" with the modification of /usr/lib/eclipse/eclipse.ini
- open a JEE perspective in eclipse
- you will notice that the "internal web browser" is disabled ( greyed out ) in the menu "window, preferences, general, web browser"
- in "GTK3 mode" ( default GUI in eclipse ) this bug doesn't occur
- this bug is probably due to a recent "pacman -Syu" and some package related to webkit
