This is exactly the solution. I was now able to reproduce the bug by restoring a backup of an old version of my eclipse configuration. As before starting the help resulted in the NoClassDefFoundError. Then I started "eclipse -clean" and the help system is working again. So I assume that when I switched from the original eclipse build to the Debian version old plugin data where still cached in the configuration. And "eclipse -clean" caused eclipse to recognize the new plugin data. Thanks for your help! Markus -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
