Similar to issue 196138

Comment 3 Jaroslav Tulach 2012-12-06 10:13:35 UTC

Amazing. Has anybody seen the code:
http://hg.netbeans.org/ergonomics/file/f8680cfa6608/openide.util.lookup/src/org/openide/util/lookup/implspi/ActiveQueue.java

line 184: LOGGER.finer("dequeued reference");
line 59:  private static final Logger LOGGER = Logger.getLogger(ActiveQueue.class.getName());

How can the NPE happen on line 184 is a mistery to me. Let's consider it a JDK bug.

Hopefully it is harmless, or does the reporter has other opinion?

Please reopen if reproducible with the latest update of Oracle JDK 1.7, thanks.
