Error calling clear() via JMX on a transactional cache with autoCommit=false ---------------------------------------------------------------------------- Key: ISPN-2865 URL: https://issues.jboss.org/browse/ISPN-2865 Project: Infinispan Issue Type: Bug Components: JMX, reporting and management Affects Versions: 5.2.1.Final Environment: Apache Tomcat on Linux and Windows Reporter: Marc Richards Assignee: Mircea Markus Labels: 5.2.x Fix For: 5.2.3.Final, 5.3.0.Final Calling clear() via JMX (e.g. JConsole) on a transactional cache with autoCommit="false" fails with an IllegalStateException. Looking at the source code it would appear that the expectation is that the call to clear() would have been wrapped in a transaction, however that is not currently happening for calls made via JMX if autoCommit="false". The [clear() method in CacheImpl.java line 321|https://github.com/infinispan/infinispan/blob/5.2.1.Final/core/src/ma...] calls getInvocationContextWithImplicitTransaction() which tests to see if there is an ongoing transaction [on line 482|https://github.com/infinispan/infinispan/blob/5.2.1.Final/core/src/ma...] . If autocommit is turned on, it will automatically create an implicit transaction, but if it is off as I had it, it will simply call createInvocationContext() and throw an IllegalStateException when it sees that the transaction is still null in [TransactionalInvocationContextContainer.java on line 112|https://github.com/infinispan/infinispan/blob/5.2.1.Final/core/src/ma...]. I currently work around the issue by setting autoCommit="true", but that is not an ideal solution.
