Tom Barber created JOSHUA-267:
---------------------------------
Summary: Java seems to swallow C exceptions
Key: JOSHUA-267
URL: https://issues.apache.org/jira/browse/JOSHUA-267
Project: Joshua
Issue Type: Bug
Reporter: Tom Barber
Priority: Minor
I compiled joshua on Ubuntu and copied it to another box of the same type, but
missing various C bits that were required at build time, but Joshua doesn't run
and tells me:
Input 0: <s> berkeley works fine , but the pipeline fails in next steps </s>
Input 0: Collecting options took 0.000 seconds
Input 0: FATAL UNCAUGHT EXCEPTION: null
java.lang.NullPointerException

Looking at the code its where it passes off to a decoder, which if it doesn't
appear, must surely throw some error that we don't see?
