this is probably native code bug in openjdk. ----- Original Message -----

Caution on upgrading your dev machine to Fedora 20. GWT compilation of "safari" (for Chrome) causes a segfault during the build. Strangely, the build appears to work, so I'm not sure what the net effect of the segfault is.
If you only compile for gecko (Firefox) [the default], you won't see the segfault.
In other words, make clean install-dev PREFIX=$HOME/ovirt-engine DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8,safari" causes the segfault
But make install-dev PREFIX="$HOME/ovirt-engine" works just fine.
I've duplicated this with with both OpenJDK and Oracle JDK.
I can confirm this on my F20 system with OpenJDK as well. So far I have not observed any problems with the resulting build.
I've since duplicated it building a different GWT project, so I'll report the bug against GWT.
I also see a similar crash in Eclipse if Eclipse is using webkit (the default) AND Google Talk is installed. Either uninstalling GTalk or using -Dorg.eclipse.swt.browser.DefaultType=mozilla works around that. So the GWT bug might be a JDK bug. Thoughts?
