When attempting to view JEI recipes for rotten flesh, when switching to a different page I get this NullPointerException:

MC: 1.9
Forge: 12.16.1.1907
RandomThings: RandomThings-MC1.9-3.7.jar

Only seems to happen in multiplayer, nothing in the server logs, just an IOException and a disconnect message.

Disregard, apparently the server did not have the RandomThings mod uploaded properly, it was size 0. Must have been corrupted in transfer. After re-uploading the issue does not seem to persist.
