I've sent this to bugzilla #120.
If the content header length exceeds 2K Orion throws the following
exception:
Orion 1.3.8 throws an java.lang.ArrayIndexOutOfBoundsException

This is the JSP I wrote to test this case: Set the "length for next action"
to
1000 and hit next a couple of times and you will see the error.
Thanks,

<p> This JSP is to test sending URLs. As the size of the action url
on
the form
and the size of the what is stored in the headers nears 2000 bytes,
Orion has
problems parsing the data. This can be easily be reached by
submitting
the form
twice while creating an form action of 1000 characters<p>
