Problem comes from the fact the commit operation does not switch to 'out of classpath' handling mode in this scenario. It should as soon as the unit primary is excluded, and working copy is not a primary wc(as in this case, we have special support in the model to open them).
Created attachment 7990 [details] patch
Patch wasn't quite right. It also needs to check whether the root is on classpath, as exclusion check doesn't do it for free. Fixed.
Test is needed. Make sure that test fails with CommitWorkingCopyOperation 1.44 and that it passes with 1.45.
Added regression test WorkingCopyNotInClasspathTests.testCommitWorkingCopy2().
Verified for 3.0 using build I200403250010.
