On a local test run of all tests in /runtime I got the following failure:

----------System.out:(2/734)----------

----------System.err:(14/974)----------
java.lang.RuntimeException: Load factor too high, expected MAX 5.0, got 467.30841121495325

But I have no idea how this came about because the test doesn't report the output from PrintSystemDictionaryAtExit. It should dump all the output before throwing the exception.
