When running in an environment in which code is invoked from maven -> junit -> mockit into test code, under 17015b33_x86_64 - odd NPEs are received in java.io.FileInputStream in attempting to close a file descriptor following a classloading attempt using a URLClassLoader. It appears that instance fields are not getting set on object creation properly. When trying later versions of the JDK, including this latest version of 7u40, instead of the NPEs we get core dumps - for every attempted execution.
I've saved the core dump file if you need it.
