JDK-4907359 - JNI spec should describe functions more strictly
Description
"When AttachCurrentThread() fails you should not
trust the value in the penv argument, even though I could not actually
find a relevant passage in the JNI "spec" book which states that to be
the case (it does include code snippets that promote that use, but confusingly
also snippets that do not check the return value before dereferencing
the penv argument)."

This should be cleaned up.
