Ran into a bit of a problem in the WTP 3.10.0.M6 build in that there are 2 dali features - org.eclipse.jpt.dbws.eclipselink.feature and org.eclipse.jpt.jaxb.eclipselink.feature - which can't find dependent package com.sun.codemodel, so can't be installed.
As such I've removed these 2 features from the simrel site here  and will need to do the same for EPP, since the build is failing .
Here's a gerrit for that removal .
In future, could I get push rights to make changes to the jee and reporting packages directly, once the gerrit verification passes?
I hope we can get these re-added for M7, but for now they need to be removed.
