Uid comparison fails for max uid -------------------------------- Key: JBTM-1989 URL: https://issues.jboss.org/browse/JBTM-1989 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public(Everyone can see) Components: Common Affects Versions: 5.0.0.M6 Reporter: Michael Musgrove Assignee: Michael Musgrove Fix For: 5.0.0.Final The largest Uid (Uid.MAX_UID) is defined to have the string form 7fffffff:7fffffff:7fffffff:7fffffff:7fffffff The first 2 components are hex values corresponding to Integer.MAX_INT but these two fields end up being converted into 2 longs to populate the field long[] hostAddr hostAddr. Consequently most Uids will end up being greater than MAX_UID (which causes problems when trying to order last resources last in the intentions list. The fix is to use "7fffffffffffffff:7fffffffffffffff:7fffffff:7fffffff:7fffffff" for MAX_UID
