Package: jamvm
Version: 1.5.3-2
Severity: normal
When running a main class loaded from a Jar file and hen configuring
java.util.Logging to
log to a FileHandle, if the logging formatter includes a SimpleDateFormat
object the
formatter fails to initialize with a java.lang.NullPointerException.
If the main class is un-jarred and then run again, loading from the file system
this time,
the logging formatter does initialize correctly. Here is an example test case,
where
I first run a simple main class via the file system and it does not throw an
error. The
second time I run from a Jar archive, and configure the logging properties from
an
absolute file path, and it still completes successfully. The third time I run
from a
Jar archive again, but this time include the file system in the classpath and
configure
the logging properties as a relative path -- and the exception is thrown in
this case.
