So that "./hotspot/test/runtime/StackGuardPages/testme.sh" fails because $TESTNATIVEPATH is empty, and also other ".java" (like "./hotspot/test/compiler/calls/TestDirtyInt.java") tests fail because a nativepath is being expected in -Dtest.nativepath.

It sounds like a test bug if different tests require different settings 
for -nativepath.
