If its just a compile test (ie test for successful compilation, or test 
that compilation fails correctly), then it should go in libjava.compile. 
If its a runtime test, ie you want the testuite to run the code and 
check the output, then it should go in libjava.lang.

The one test that is in subdirectory doesn't actually work - is doesn't 
get compiled. However, for libjava.compile if you put a main() class in 
the top-level directory that refers to source files in a sub-package, 
then that is sufficient to test source compilation . This is what the 
tests that use the "support" package do. I don't think there is a way to 
actually link & run a test case spread across multiple packages, however.
