I suppose you mean NoClassDefFoundError caused by ClassNotFoundException.
As far as I got recently working on similar NoClassDefFoundError issue explicitly building library is not a good idea (JTReg recommends build dependent code, but this should be done by all tests, otherwise it can cause failures of other tests).
And some time ago a lot of such explicit build actions were removed from tests.
