--- Comment #2 from Fredrik Tolf <[e-mail]> ---
I just want to report that I'm getting something very similar, again when the
JVM tries to create a Windows selector. I'm getting this on OpenJDK 25.0.2, so
it seems to be alive across many Java versions.

I'm only getting automated reports of this every once in a while, so I'm not
entirely sure what the circumstances are, but I suspect this is Steam trying to
launch a Java game I've put on there through Proton (even though there is a
native Linux build available, so this is very much not my choice).

I can't say I'm familiar with the internals of OpenJDK's Windows selector
implementation, but as I understand, they use a Unix domain socket (for some
reason), for internal wake-up purposes.

This is my Java stacktrace (coming through a custom formatter for my error
reporting system, just to explain the unorthodox style). It seems to be the
exact same bug from what I can tell:

java.lang.NullPointerException
Cannot read the array length because "<parameter1>" is null

Just to be clear, my own last code is the "Utils.java:154" line, which is just
a simple call to `Selector.open()`, so it's hard for me imagine there is
anything *I* could be doing differently.

--- Comment #3 from Fredrik Tolf <[e-mail]> ---
Also, since I probably wasn't quite clear enough, the reason I'm suspecting
this is a Wine problem is because the only reports I'm seeing about this have
metadata claiming to be running on Windows 10, but using the Mesa OpenGL
drivers, suggesting to me pretty strongly that it's running in Wine. They're
also claiming to be using Mesa 26.1.2-arch2.1, which suggests to me that it's
SteamOS.

--- Comment #4 from Fredrik Tolf <[e-mail]> ---
Digging around in the OpenJDK sources indicates that the Java-side code gets an
unexpected Java null value back from the native function that tries to fetch
the local name for the Unix-domain socket in question. This function lives in
"src/java.base/windows/native/libnio/ch/UnixDomainSockets.c", and looks thus:

jbyteArray sockaddrToUnixAddressBytes(JNIEnv *env, struct sockaddr_un *sa,
socklen_t len)
{
    if (sa->sun_family == AF_UNIX) {
        int namelen = (int)strlen(sa->sun_path);
        jbyteArray name = (*env)->NewByteArray(env, namelen);
        if (name != NULL) {
            (*env)->SetByteArrayRegion(env, name, 0, namelen,
(jbyte*)sa->sun_path);
            if ((*env)->ExceptionCheck(env)) {
                return NULL;
            }

        return name;

    return NULL;

JNIEXPORT jbyteArray JNICALL
Java_sun_nio_ch_UnixDomainSockets_localAddress0(JNIEnv *env, jclass clazz,
jobject fdo)
{
    struct sockaddr_un sa;
    int sa_len = sizeof(sa);

    if (getsockname(fdval(env, fdo), (struct sockaddr *)&sa, &sa_len) ==
SOCKET_ERROR) {
        JNU_ThrowIOExceptionWithLastError(env, "getsockname");
        return NULL;
    }
    return sockaddrToUnixAddressBytes(env, &sa, sa_len);
}

So my interpretation here is that Wine's getsockname() returns a sockaddr that
doesn't have AF_UNIX for its address family. Different values for
AF_UNIX/AF_LOCAL, or is sun_family perhaps mistakenly just not filled in it
all?
