---------------------------------------

>From email thread:

Guys,

I'm looking at MRUAlgorithmTest.testMRU() on HEAD, and suspect there may be a bug.

When a node added event occurs,
BaseEvictionAlgorithm.processAddedNodes() is called.  If the node entry is already in the eviction queue, the timestamp and number of node visits are updated, and the method returns.

In the specific case of MRU, there is nothing here to move this node to the head of the MRUQueue, which is why the test fails.

Have I misunderstood something, or is this a genuine bug?

Also, not quite sure how it works on the 1.4.0 branch - perhaps a bug fix that was not ported to HEAD?
