8172971: java.management could use System.Logger

[Daniel Fuchs]

Hi,

Please find below a patch for:

8172971: java.management could use System.Logger
https://bugs.openjdk.java.net/browse/JDK-8172971

webrev:
http://cr.openjdk.java.net/~dfuchs/webrev_8172971/webrev.00/

I have also added a new test:
test/sun/management/LoggingTest/LoggingTest.java

This is a simple smoke test that verifies that we still
get expected debug traces when creating and populating
the platform MBeanServer.
This test should always pass - whether the fix is present
or not.

best regards,
