A couple of data points:

The NPE is because libjava.dylib is handing a null value to Hashtable, for the key "user.language", in System.c.

This happens also for me, using a Java 7 libjava.dylib.  The bug is oddly sensitive to the setting of DYLD_LIBRARY_PATH, and something about the test_gamma script makes it worse.  See demo below.  The bug seems to be in the test_gamma script, but I haven't figured out how it works.
