Hi,
I have code needs to determine if the current thread is UI thread or not,
since my plugin can not depend on any UI plugins, so I can not use
Display.getCurrent() to do so, is there any other way I can check the
thread? Will the UI thread in eclipse has higher priority?
Thanks for your help!

Couldn't you just check Display.getCurrent(). The javadoc seems to say
that if it returns null you are not a UI thread...
