> 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/main/java/org/infinispan/CacheImpl.java#L321] 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/main/java/org/infinispan/CacheImpl.java#L482] .  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/main/java/org/infinispan/context/TransactionalInvocationContextContainer.java#L112].
> I currently work around the issue by setting autoCommit="true", but that is not an ideal solution.
