PQ69096, 4.0.5: An IllegalArgumentException displays
the stack
Downloadable files
Abstract
When an IllegalArgumentException is thrown, the default
error page does not display, and the error reporter displays the
stack.
Download Description
Users affected
WebSphere® Application Server installations receiving query string
parameters that are not valid for JSP™ requests are affected by this
problem.
Description
Customer-defined error pages are not executed when query string parameters
that are not valid are passed to a JSP resource. An uncatchable
IllegalArgumentException is thrown when a query string that is not valid
is sent to a JSP resource. The JSP Processor parses the query string prior
to executing the JSP in search of the request parameter jsp_precompile.
Since the default error page is also a JSP, the forwarding to the error
page also fails with the same exception.
This prevents the custom error page from starting and results in a
WebSphere-generated error page being sent to the client.
Conclusion
Exception handling to catch IllegalArgumentException when checking if the
request parameter jsp_precompile was sent with the request has been added.
