[jira] Created: (IBATIS-533) Thread blocking on AutoResultMap
Thread blocking on AutoResultMap
--------------------------------
Key: IBATIS-533
URL: https://issues.apache.org/jira/browse/IBATIS-533
Project: iBatis for Java
Issue Type: Bug
Affects Versions: 2.3.2
Reporter: Robert McIntosh
Priority: Critical
The AutoResultMap class' getResults method is synchronized. This causes threads to get backed up when a moderate load is on the system. The end result is that our heap gets overloaded and eventually the app stops.
it appears from looking at the code that the synchronize only needs to be on the remapping and/or initial construction of the result mappings. Would suggest making the the initialize method synchronized at the very least, so that once the mapping is created no blocking of threads is necessary.
May be related to issue 519 as well.
