Fixed.

> ExplodedModuleBuilder is useful infrastructure but I'm not sure that test/tools/lib is the right place as that location seems to be for jimage infrastructure (I've often thought this should move). Maybe test/lib/testlibrary would be better because that there is where ModuleUtils and the other test infrastructure used by these tests is. Also just wondering if there is a better name for this class as it supports both creation and compilation, maybe it should be in ModuleUtils as Builder or ModuleMaker (you might have tried a few names already). Once this is in then we might look at changes some of the existing tests to use it.

What about renaming it to test/lib/testlibrary/ModuleSourceBuilder.java?
