I'm not sure how bug 142530 could cause this since no .jar file is involved here.
I see. Is indeed already broken in I20060620-1010 (works in 3.2_M20060609-1217).
Changed SetContainerOperation#executeOperation() to catch the CoreException when touching the project and ignore it if it is an external Java project. Added regression test ReconcilerTests#testExternal2(). Released for 3.3 M1 in HEAD.
Why got it introduced?
Anything having to do with classpath was completely rewritten recently.
Verified for 3.3 M1 using build I20060807-0010.
