RequestCorrelator causes frequent boxing and autoboxing by using a Map<Long,Request> ------------------------------------------------------------------------------------ Key: JGRP-2044 URL: https://issues.jboss.org/browse/JGRP-2044 Project: JGroups Issue Type: Enhancement Reporter: Sanne Grinovero Assignee: Bela Ban Priority: Minor Fix For: 4.0 The JFR profiler is highlighting a significant amount of boxing and autoboxing, as the request is is treated as a {{long}} but this is used as an key for the {{Map<Long,Request>}}. We could try to either consistently use {{Long}} rather than {{long}}, or even better figure out an optimal data structure to replace the implementation of the Map to not require boxing of the keys.
