---------------------------------

             Summary: NPE while deserializing an XMI in a PEAR context
                 Key: UIMA-6485
                 URL: https://issues.apache.org/jira/browse/UIMA-6485
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
    Affects Versions: 3.3.1SDK
         Environment: * SO: macOS 12.6.2
 * OpenJDK Temurin 1.8.0_322
 * uimaj-core 3.3.1
            Reporter: Beni Santos


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.
