Build Identifier: I20110613-1736

The imported package list in jetty's manifest file limits the version of javax.servlet to 2.5 or 2.6. The other dependent files of org.mortbay can load javax.servlet version of 3.x which leads to problems in the User Assistance area like this stacktrace:

Plugin dependencies of org.eclipse.equinox.http.jetty show the different javax.servlet versions used are 2.5 and 3.0. If javax.servlet version 3.0 is removed from the list of loadable plugins then UA works again. 


Reproducible: Always

Steps to Reproduce:
1.Install Eclipse 3.7 sdk
2.unzip orbit-R20110523182458.zip to eclipse/dropins/gmfbase
3.Start eclipse
4.Hit F1 to open Help. No help text appears, log contains error message
5.Same with Help->Help contents
5. Check plugin dependencies view for

Finishing the last sentence:
Check plugin dependencies view for org.eclipse.equinox.http.jetty

We cannot tolerate servlet 3.0 until we have support for jetty 8.

Thanks Thomas,
is there an ETA for this?

Would it be possible to change the dependencies so that none of plugins jetty depends on (mortbay, etc) would use servlet version 3.0? 
The way it is now means that jetty (and the help system) is unusable, right?

Removing the plugin javax.servlet_3.0.0.v201103241727.jar solves the problem. I do not know who installed it. But plugin dependencies should be stricter to avoid problems like this one.
