Hi,
Please find below a patch for:
8065991: LogManager unecessarily calls JavaAWTAccess from within
a critical section
https://bugs.openjdk.java.net/browse/JDK-8065991
Webrev:
http://cr.openjdk.java.net/~dfuchs/webrev_8065991/webrev.00/
Note: https://bugs.openjdk.java.net/browse/JDK-8065709
shows a thread dump where this is causing a deadlock between
AWT and LogManager. However - fixing this particular deadlock
may require more than modifying LogManager. The fix proposed
here should hopefully make JDK-8065709 less likely - but will
not guarantee that the issue discribed in JDK-8065709 is
fully fixed.
I have included a testcase that replaces the implementation of
JavaAWTAccess and emulates AppContext.getAppContext().
The test fails in deadlock without the change, and passes with
it (though only because LogManager is pre-initilized in main()).
best regards,
