Spark Crash on start

When i start spark it chrashes.

I read this on the log:

org.jivesoftware.spark.util.log.LOG error

ALLVARLIG: Bookmark plugin loaded earlier then BookmarkUI. BookmarksListener Events wouldn’t work!

any ideas why it keeps crashing would be helpful

to be more specific spark works after starting it. But when i open a conversation window it crashes

Hi

what version of Spark did you install? 2.6.3 release of the 2.7.0 alpha. Do you use the online version or the one with a build in JRE? Any home made plugins?

A fix might be the to uninstall Spark and clean the plugin folder in the user profile.
