OPENJPA-2575: temporary set TCCL to _tmpClassloader
This prevents using the wrong ClassLoader during OpenJPA bootstrap
which might lead to memory leaks.

> Hi
> if there is a temp loader in
> org.apache.openjpa.enhance.PCClassFileTransformer#transform0 then it should
> be the context where classes are loaded during the enhancement (transform0).
> typically "new Project().loadClass(new ByteArrayInputStream(bytes),
> _tmpLoader)" shouldn't be done outside of _tmpLoader contextual loader.
> Standard Thread.currentThread().setContextClassLoader(_tmpLoader); then
> setContextClassLoader(old) try/finally solves it.
> Side note: this issue has been reported originally on tomee@.
