Hello, thanks a lot for your quick answer.
I just created http://jira.qos.ch/browse/LBCLASSIC-262 , please ask me for any details. Because we use a very old version of IBM JVM, I looked at the IBM JVM fixes, searching something about LinkedHashMap, but didn't find anything. Do you have already planned a new release of Logback (0.9.29), including the patch for LBCLASSIC-255?
