[jitsi-users] Jitsi crashes on Java 7 or 8 under Linux?

Has anyone experienced very frequent crashes or failures to start
Jitsi when it runs on Java 7 or 8 under Linux or crashes when opening
or closing "harmless" dialogs such as About Jitsi?

I've been experiencing such crashes for a very long time with various
updates to Java 7 and 8. Today I finally tracked it down to
https://bugs.openjdk.java.net/browse/JDK-8041442: JVM crashes after
calling "UIManager.getSystemLookAndFeelClassName".

I'd like to gather feedback because a workaround will result in the
use of the "cross-platform look & feel" with Java 7 and 8 under Linux.
