It's the old "fetch an environment problem" (the JNI function 
GetEnvironment). This was (briefly) discussed here:
http://gcc.gnu.org/ml/java/2006-10/msg00058.html
Somehow I don't think using -fno-strict-aliasing is worth it to capture 
this one case...
The other warnings use JVMTI's Allocate function which does something 
similar. IMO, we should just fix the warnings.
