java.lang.Exception: Validation failed: input param is NULL

Off the top of my head something like this

(?i)java.lang.Exception:\s?<field>(.+)$

This works for my data (YMMV) at search time:

"java.lang.Exception" | rex field=_raw "(?ms)java.lang.Exception(?P<exception>.+)"

add (?ms) on the beginning - the s is dotall, and the m is multi-line.

 (?ms)java.lang.Exception:\s?<field>(.+)

Is that the entire event? I ask because of the mis-matched paren. Is it a single-line or multi-line event?
