[infinispan-issues] [JBoss JIRA] (ISPN-7667) Use ArrayDeque for transaction context iterator

Use ArrayDeque for transaction context iterator ----------------------------------------------- Key: ISPN-7667 URL: https://issues.jboss.org/browse/ISPN-7667 Project: Infinispan Issue Type: Bug Reporter: William Burns Fix For: 9.0.0.Final Transaction iterator stores entries from the context into a List. It then removes the first element from that as it processes those entries. This should use an ArrayDeque to have constant time removals (where as ArrayList needs to move entries to compensate removing from the front).
