[jira] [Commented] (UIMA-6274) Setting feature on builtin JCas cover class that was loaded before initializing TypeSystemImpl fails

["Richard Eckart de Castilho (Jira)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-6274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17215206#comment-17215206 ] 

Richard Eckart de Castilho commented on UIMA-6274:
--------------------------------------------------

[~serge712] that appeared to be a very specific edge case in an optimized part of the JCas initialization logic - but I think I found a good fix for it.

Can you verify that my changes work in your environment?

> ProxyFactory f = new ProxyFactory();
> f.setTargetClass(JCas.class);
