[jira] Commented: (UIMA-780) CDE hangs when processing AEs with very high initialization time (adding the AE to the aggregate or saving the descriptor)

["Marshall Schor (JIRA)" <ui...@incubator.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568749#action_12568749 ] 

Marshall Schor commented on UIMA-780:
-------------------------------------

The CDE calls the framework code to "validate" the descriptor before saving it.  The framework validation code calls produceAnalysisEngine, with a flag indicating that this call is for validation purposes only.

The framework code goes so far as to actually load the class, but because the validation flag is on, it doesn't make an "instance" of it.  

Just loading the class, however, runs the class's "static" initializers.  If these initializers take a lot of resources, then that would explain what's happening.  Do you know if that is the case?   If so, is it possible to move the initialization to the "initialize" call, instead of doing it at "load" time?

> The CDE repeatedly hung when trying to add an AE with high initialization time into the aggregate. When I finally successfully added it through editing the source xml, it hung again while trying to save the descriptor. It appears that the CDE is trying to initialize the annotator (CPU usage 200+%, using 5.7G of memory). I verified this by having the annotator in question load a toy dictionary and the problem disappeared.
