[jetty-users] rewrite rules

[Michael Dykman <mdykman@xxxxxxxxx>]

I am trying to get some rewrite rules to weork.  This is an
application I had running well under Jetty 8 (using the Ubuntu 12.04
default installation) but I am stymied trying to bring it to Jetty 9.

I have rewrite rules configured in a Configureation file (listed below in full)

It appears that my rewrite rule is matching, the rewrite occurs and
then I hit a NullPointerException while trying to end the rewrite
portion.

Any thoughts?
