[wtp-releng] Compile errors in org.eclipse.jst.server.generic.core?

[David M Williams <david_williams@xxxxxxxxxx>]

In the latest 3.3 build, there were a number of "illegal
cast" compile errors in org.eclipse.jst.server.generic.core. 

Was this due to a change in org.eclipse.jst.server.generic.core?


I ask because I am fairly sure all the pre-reqs were
exactly the same as previous build (where there were no compile errors)
but I did change the version of our "base builder" which (mostly)
means previously builds were compiled with a 3.6 based JDT compiler, but
now are compiled with a 3.7 M4 based compiler. Could there have been a
change there to cause this? Or a change in defaults ... former warnings
now caught as errors?  

Even though we do not have a "declared build"
this week, I'd appreciate understanding this issue quickly (EOD Wednesday?),
to know if we have a problem with our M4 deliverables ... or, if someone
just casually checked in some code with errors? 

Thanks,
