Uncaught exception handler should exit on a java.lang.Error
-----------------------------------------------------------
Key: ZOOKEEPER-1442
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1442
Project: ZooKeeper
Issue Type: Bug
Components: java client, server
Affects Versions: 3.3.5, 3.4.3
Reporter: Jeremy Stribling
Assignee: Jeremy Stribling
Priority: Minor
The uncaught exception handler registered in NIOServerCnxnFactory and
ClientCnxn simply logs exceptions and lets the rest of ZooKeeper go on its
merry way. However, errors such as OutOfMemoryErrors should really crash the
program, as they represent unrecoverable errors. If the exception that gets to
the uncaught exception handler is an instanceof a java.lang.Error, ZK should
exit with an error code (in addition to logging the error).
