Test JdwpListenTest.java has a debuggee listening on
10.133.185.241:56804 and was expecting to fail to
attach/connect via 127.0.0.1:56804. However, it was
able to attach/connect so the test failed.

Test JdwpNetProps.java had a debuggee listening on
localhost:56804 and it was expecting to attach/connect
via 127.0.0.1:56804. However, it failed due to
java.net.ConnectException: Connection refused.

The debuggee from JdwpNetProps.java connected with
the client from JdwpListenTest.java which was expecting
to not connect (so the test failed).

The client from JdwpNetProps.java failed to connect to
its debuggee because the client from JdwpListenTest.java
was already connected so that test failed.
