TEST_BUG: java/rmi/Naming/legalRegistryNames fails if registry already running

TESTFAIL:java/rmi/Naming/legalRegistryNames/LegalRegistryNames.java

The test java/rmi/Naming/legalRegistryNames/LegalRegistryNames.java will fail if there is an RMI registry already running on the machine. The regression test TEST.ROOT file contains the line

exclusiveAccess.dirs=java/rmi/Naming

which prevents tests from running concurrently, which might cause registry port conflicts. However, if a registry is running on the machine external to the test suite, the test will fail. I'm not sure we can guarantee that a registry is *never* running on the test machines. At least, it's confusing to have this test fail if a registry happens to be running already; I had left one running on my development machine and I was surprised to see a "new" test failure.

The error is pretty obvious, but here it is:


Starting registry on default port
TEST FAILED: registry already running on test port
TestFailedException: TEST FAILED: registry already running on test port
