> Modify UIMA-As deployment descriptor to support disabling of JCAS Cache on CasPool element.
From the UIMA documentation:
> "UIMAFramework.JCAS_CACHE_ENABLED: allows you to disable the JCas cache (true/false).
The JCas cache is an internal datastructure that caches any JCas object created by the CAS.
This may result in better performance for applications that make extensive use of the JCas,
but also incurs a steep memory overhead. If you're processing large documents and have memory
issues, you should disable this option. In general, just try running a few experiments to
see what setting works better for your application. The JCas cache is enabled by default.
> To support this, the dd2spring needs to handle a new property in the DD - disableJCasCache=true/false
on element casPool. Modify UIMA-AS CasManager wrapper to add setter and getter for the new
> Also, changes are needed in DD Gui to support the new property
