Upgrade integrated coherence (FMW) cause of memory leak

Hi,
i have some trouble with default coherence cache supported with weblogic. After a couple of days the AdminServer is running into OutOfMemoryError cause of "One instance of "com.tangosol.coherence.component.net.Cluster$ClusterService" loaded by "weblogic.utils.classloaders.GenericClassLoader @ 0x70df6a28" occupies 1.399.704.448 (88,25%) bytes. The memory is accumulated in one instance of "com.tangosol.util.RecyclingLinkedList" loaded by "weblogic.utils.classloaders.GenericClassLoader @ 0x70df6a28"

On Metalink I found this Bug 12838629 - COHERENCE LEAKS RECYCLINGLINKEDLIST INSTANCES IN LOGGER.  Also, (COH-5501 - Coherence leaks RecycledLinkedList instances in Logger).
Oracle Support Document 1456791.1 (OutOfMemoryError When Coherence Logger Gets Stuck)

The solutions says upgrade to Coherence 3.7.1.4 or higher, but how can i upgrade the WLS default coherence cache?!? Is that even possible?

Howdy, Stranger!
