Start by rerunning the jdk_net_0 selection with the linked Grinder job on ppc64le_linux, then inspect the Jenkins and TRSS output for the listed java/net, jdk/net, sun/net, and sun/tools/jstatd tests. Compare the failures across the test list to identify whether they share a cause; done means the failures are explained and the affected test run passes.
