sun.nio.ch.NativeThread.current

[Martin Buchholz]

There is a mismatch between the spec and implementation of
sun.nio.ch.NativeThread.current

    // Returns an opaque token representing the native thread underlying the
    // invoking Java thread.  On systems that do not require signalling,
this
    // method always returns zero.
    //
    static native long current();

...

Java_sun_nio_ch_NativeThread_current(JNIEnv *env, jclass cl)
{
#ifdef __linux__
    return (long)pthread_self();
#else
    return -1;
#endif

...

Which is it, zero or -1?

Please file a bug.

Thanks,

Martin
