Hello all,
I'm looking for any ideas on the following issue:
https://issues.apache.org/bugzilla/show_bug.cgi?id=53958
On Tomcat 7.0.32, using embedded Tomcat, I'm seeing a
NullPointerException when using a custom error page. The page itself
is fine and loads if accessed directly. Triggering an error like a 404
results in an NPE during handling of the error page, like:
Oct 10, 2012 7:47:29 PM org.apache.catalina.core.StandardHostValve custom
SEVERE: Exception Processing ErrorPage[errorCode=404, location=/error.jspx]
java.lang.NullPointerException
at
org.apache.catalina.core.StandardHostValve.custom(StandardHostValve.java:456)
at
org.apache.catalina.core.StandardHostValve.status(StandardHostValve.java:327)
at
org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:193)
at
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99)
at
org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118)
...
Mark's tried to reproduce it and can't, even with the exact same test
case I'm running, copied in the issue there (and copied below).
I'm wondering if anyone sees an error in the configuration, or can
imagine what the issue may be from the additional details in the
issue. Or, even has time to try out the test case locally.
Best regards and thanks for any ideas.
