    Description

      Getting java.lang.ArrayIndexOutOfBoundsException
      java.lang.ArrayIndexOutOfBoundsException: -4
      at org.jgroups.protocols.Locking._getLock(Locking.java:355)
      at org.jgroups.protocols.Locking.handleLockRequest(Locking.java:424)

      that happens when lock_name.hashCode() < 0

      protected Lock _getLock(String lock_name)

      { int index=lock_name != null? lock_name.hashCode() % locks.length : 0; return locks[index]; }

          Bug - A problem that impairs or prevents the functions of the product. JGRP-1639 Locking: lock name with negative hashCode() throws out of bound exception

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
