Hi,
While testing some web applications on Jetty very quickly I ran into
the following NPE (while accessing some jsps):
java.lang.NullPointerException

After googling a bit I found the following bug reports:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=193269 and
https://issues.apache.org/jira/browse/FELIX-1032. Looks like a JRE bug
but maybe we can prevent this problem by patching Jetty (by closing
the inputstreams) ?
