Log4j shutdown patch -------------------- Key: JBAS-1978 URL: https://jira.jboss.org/jira/browse/JBAS-1978 Project: JBoss Application Server Issue Type: Patch Security Level: Public(Everyone can see) Affects Versions: JBossAS-4.0.2 Final, JBossAS-4.0.3RC1 Environment: All Reporter: Roelof Naude Attachments: jboss.logging.patch, jboss.logging.patch Original Estimate: 30 minutes Remaining Estimate: 30 minutes Currently the log4j subsystem is not properly shutdown when jboss is shutdown. This cause problems with certain log4j appenders, particularly those that make use of buffering, ie buffered io for file appenders, jdbc appenders with a sizeable internal buffer. The problems experience include: 1. when using buffered io, the BufferedWriter is not flushed, resulting in lost messages or only partially written messages 2. we have a custom JDBCAppender which only commit (auto commit disabled) after the appender's internal buffer has reach a certain size. currently the appender is not properly closed resulting in lost messages.
