java/nio/channels/AsynchronousChannelGroup/Unbounded.java failing again [win64]

This test has recently started to fail in JPRT, all sightings so far have been Windows 64-bit. The failure doesn't seem to be the test itself, it appears to be interference from tests that run previously, perhaps a connection limit. The test runs okay if changes to /othervm mode.
