Sylvain Laurent commented on IBATIS-376: ---------------------------------------- I opened a new issue IBATIS-376 for a different leak. The leak in this IBATIS-376 issue does not occur in my case because Spring's iBatis support does not make use of getLocalSqlMapSession(), but rather use openSession(). > Hot deploy issue > ---------------- > > Key: IBATIS-376 > URL: https://issues.apache.org/jira/browse/IBATIS-376 > Project: iBatis for Java > Issue Type: Improvement > Components: SQL Maps > Affects Versions: 2.2.0 > Environment: ALL > Reporter: kevin chae > Attachments: SqlMapClientCleaner.zip > > > Hi Clinton and team. > I found an interesting issue. > In case of hot deploy > ThreadLocal localSqlMapSession causes a memory leak. > As you know, iBatis calls getLocalSqlMapSession().close(); > but WAS classLoader remains in the memory after a hot deployment > because classLoader still has a reference of the ThreadLocal. > It needs to explictly set null > I tried to test with the code below and it works fine. > getLocalSqlMapSession().set(null); > I hope to improve iBatis > Otherwise iBatis works greate ! > Cheers ! -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
