Hi,

Please find below a trivial  patch for:

8152515: (logging) LogManager.resetLogger should ignore LinkageError
https://bugs.openjdk.java.net/browse/JDK-8152515


Patch:
http://cr.openjdk.java.net/~dfuchs/webrev_8152515/webrev.00/

The issue might occur at shutdown, when a handler that makes uses
of some APIs provided by an OSGI bundle which was already closed
by the shutdown process is in turn closed by the LogManager.Cleaner
thread. In that case some subclasses of LinkageError may be thrown,
interrupting the reset process and preventing other handlers from
being closed properly.

The patch proposes to trivially ignore LinkageError at shutdown while
the LogManager.Cleaner thread is running.

best regards,
