Hi folks,
There is a bug on master that I can't figure out.
The test
LmOovFeatureTest.givenInputWithDifferentOovTypes_whenDecode_thenFeaturesAreAsExpected()
fails when run on Linux without KenLM. I can repeat this problem by deleting
$JOSHUA/lib/libken.so, and running
cd $JOSHUA
mvn test
The output is
[snip]
ERROR - Can't find libken.so (libken.dylib on OS X) on the Java library path.

However, if I run Joshua manually on this test in either of the following ways,
the test works fine:
1.
cd $JOSHUA
echo a chat-rooms full | joshua -config resources/lm_oov/joshua.config
-outputformat "%f | %c"
2.
cd $JOSHUA
mvn -Dtest=LmOovFeatureTest test
Finally, the error doesn't make sense: there is nothing to do with arrays on
the specified lines, and I don't see where an IndexOutOfBoundsException could
be coming from.
Does anyone have any ideas what is going on?
