Hi, Please find below a patch that adds a new test for logging in JDK 9.
The test verifies an issue we had on JDK 7 (the test is already in 7) but since the issue was not present in 8 & 9 the fix (and test) went to 7 only. This bug is about adding the same test that was added to 7 to 9 (and then 8u). https://bugs.openjdk.java.net/browse/JDK-8029876 8029876: Add a test to verify that Logger.getLogger & LogManager.getLogManager don't throw NPE when System.out == null original fix + tests pushed in 7: http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/rev/3ba8d15adade webrev (trivial copy of the test to jdk9-dev): http://cr.openjdk.java.net/~dfuchs/webrev_8029876/webrev.00/ best regards, -- daniel
