Hi all, Many of us have identified a major bug leading to Eclipse crash when using JBT 4.2.0.Alpha1 and Eclipse Luna. https://issues.jboss.org/browse/JBIDE-16280 , https://issues.jboss.org/browse/JBIDE-16308 , https://issues.jboss.org/browse/JBIDE-16290 . Xulrunner binaries we have don't work on GTK3 (which is next Eclipse default implementation for SWT on Linux). Apparently there is no xulrunner available which works with GTK3, and anyway, the dependency on discontinued JavaXPCom seems to show that it's impossible to find a set of compatible SWT/GTK3/XulRunner/JavaXPCom libraries that can work together. This makes that currently, we don't have any way to get XulRunner and VPE working on Linux. They currently crash the workbench, but even if we workaround that (by checking the gtk version used and avoid invoking xulrunner when using GTK3) we can't have this feature working. What do we do from here? It seems like the recommended way (from old messages on JavaXPCom list) is to use WebKitGTK+ on Linux instead of xulrunner. For more uniformity, it would require to get rid of xulrunner for other OS and rely fully on Webkit and a Java binding such as webkit driver. Is this a right path to follow? If yes, this should be started very soon, except if we prefer dropping the whole VPE in favour of something else.
