             Summary: SYM/ASYM_ENCRYPT: don't use WeakHashMap for old ciphers
                 Key: JGRP-2075
                 URL: https://issues.jboss.org/browse/JGRP-2075
             Project: JGroups
          Issue Type: Task
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.6.10, 4.0


Currently we use WeakHashMap, but should not, reasons outlined below. We could replace it with a LazyRemovalCache.

TL/DR: Please don't use WeakReferences, SoftReferences, etc. to cache
any data which might point to native memory. In particular, never do
this with instances of java.security.Key. Instead, implement either
some kind of ageing strategy or a fixed-size cache.
