EVALUATION Neither the Solaris nor Linux JDK implementation seems to support setting native thread names (though there seems to be an entry point in the latest Linux libpthread, pthread_setname_np(), that does so), but since OSX does, the reference to JVM_SetNativeThreadName exists in JDK native code, thus might be linked against, thus should be exported.

EVALUATION Ok.
