Description Konstantin Kolinko 2011-06-21 13:13:00 UTC
If formatter assigned to org.apache.juli.FileHandler in logging.properties is misconfigured and fails to load,
the FileHandler starts without formatter and fails with an NPE later.

To reproduce: assign some bogus value to

When Tomcat starts, the following will be printed at the console:

java.util.logging.ErrorManager: 4
        at org.apache.juli.FileHandler.openWriter(FileHandler.java:377)
        at org.apache.juli.FileHandler.<init>(FileHandler.java:99)
        at org.apache.juli.FileHandler.<init>(FileHandler.java:90)

I think we can be more tolerant to this configuration error and fall back to the default formatter. I will commit a fix shortly.
