ObjectLockingIndexedCollection's StripedLock does not handle negative hashcodes

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a class that overrides hashCode method and produces a negative hash 
code.

2. Create an indexed collection of the class created in step 1 that is backed 
by an ObjectLockingIndexedCollection.

3. Attempt to add an instance of the test class to the collection.

What is the expected output? What do you see instead?
Expected: object added to collection.
Instead: ArrayIndexOutOfBoundsException

What version of the product are you using? On what operating system?
1.2.6, Windows 7 Enterprise


Please provide any additional information below.
The StripedLock class needs to account for negative hash code values to avoid 
indexing into the array of locks with a negative index value.

Thanks for reporting this.

It's now fixed, and the fix is in CQEngine 1.2.7. It should sync to Maven 
central in the next few hours.
