A DESCRIPTION OF THE PROBLEM :
When using Logger.getAnonymousLogger or LogManager.getLogManager().getLogger in an applet a NPE occurs on the second load of the applet in the browser session.

If the browser is restarted the applet loads fine until the next reload.

REGRESSION: I could only choose 7 update 25 or 7 update 40 in the regression drop down. The issue only occurs since 7 update 25 but not in 7 update 21

REGRESSION.  Last worked in version 7u25

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create an applet from the code below.
2. Load it in a browser
3. Reload the page with the applet

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No NPE on reload
ACTUAL -
NPE on reload
