CacheContinuousQueryAsyncFailoverMvccTxSelfTest.testMultiThreadedFailover sometimes finished with OMM.

Heapdump analyze showed that leak happened in IgniteTxManager.idMap, this map contains *2_097_152* instances of GridNearTxLocal with *ACTIVE state* and *without* finishFut *and prepFut.*

 
{code:java}
while (!updated) {
 try {
 prevVal = (Integer)qryClnCache.getAndPut(key, val);
updated = true;
 }
 catch (CacheException e) {
 assertSame(atomicityMode(), CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT);
 }
 }
{code}
 

 

Possible the CacheException is common and may hide wrong cases. Change it at specific (ignite-10976).
