Bad attempt to compute absolute value of signed 32-bit hashcode. If the hashcode is Integer.MIN_VALUE, then the result will be negative as well (since Math.abs(Integer.MIN_VALUE) == Integer.MIN_VALUE). Fix: Math.abs(Integer.MIN_VALUE & FFFFFFF0), removing -2^31 as a possibility.

Condition.await() not in loop. If the object is used for multiple conditions, the condition the caller intended to wait for might not
be the one that actually occurred. Fix: Put the if statement in a while loop. At locking.java:[line 186] in method org.jgroups.protocols.Locking.down(Event)

Field isn't final but should be. A mutable static field could be changed by malicious code or by accident from another package.
Fix: Made the field final. At PartitionedHashMap.java:[line74] Field org.jgroups.blocks.PartitionedHashMap.methods
