I've just installed the new JDK7u13 and I've recompiled with no errors an unchanged applet with java.util.logging.* packages. It worked fine with 7u11 version. The applet showed info messages by console, and saved them into log files too. But now, none messages are showed. I've revised logging.propierties in jre/lib and it's correct. I've tried with a new simple standalone program and it works. Why doesn't work in applet? Any idea?
