 # JVMTI tests
 vmTestbase_nsk_jvmti = \
- vmTestbase/nsk/jvmti
+ vmTestbase/nsk/jvmti \
+ vmTestbase/nsk/share/ExceptionCheckingJniEnv

This is now causing failures when running tier5:

open/test/hotspot/jtreg/TEST.groups: group vmTestbase_nsk_jvmti: file not found: vmTestbase/nsk/share/ExceptionCheckingJniEnv
Error: Group is invalid: vmTestbase_nsk_jvmti

The file referenced is:
test/hotspot/jtreg/vmTestbase/nsk/share/jni/ExceptionCheckingJniEnv.cpp

There seems to be a /jni missing in TEST.groups.
