I encountered this problem during my Kestrel Build I Quick Look.
The OS on which the test was running is Solaris 2.6. I have
reproduced the bug with the following java command configs:

    - green threads, JIT enabled
    - green threads, no JIT
    - native threads, JIT enabled
    - native threads, no JIT

I retested using Kestrel Build H and the failure does not occur.

From tests/url/GetURL.java:

            } else {
                logdebug("parsing URL: " + theurl);
                URL url = new URL(theurl);
                connected = false;
                for(int i=0; i<3; i++) {
                    try {
                        logdebug("opening stream to URL: " + theurl);
                        in = url.openStream(); <=== NULL pointer execption
                        connected = true;
                        break;

Here is the no-JIT portion of the reproduction log:

I just retested Kestrel Build I and the failure still occurs with a
different stack trace:

I reproduced the failure using both the java.net test suite *and* the
attached archive 4249722_repro.tar.Z. Was the archive used to test
the proposed fix? It certainly reproduces the bug with Build L so I'm
curious if the bug is not always reproducible.
