--------------------------------------------------
Thx :)
> 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
> Priority: Major
>
> 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.
