Description

When running an AAE in a PEAR context (uimaj-core 3.3.1), if a CAS Multiplier tries to populate a new CAS while loading it from an XMI file, a NullPointerException is thrown by the method maybeMakeBaseVersionForPear of the class CASImpl.java (line 1536).

 

Complete failing example here: https://github.com/benisantos/uima3-xmi-deserializer-in-pear

 

Workaround: use the uimaj-io-json library and de/serialize JSON instead of XMI.
