Makes TestPullUpdatesApplied  use proper synchronization instead of relying on Thread.sleep()
Makes sure that the ordering of BrickElements in PersistenceWindowPool does not change while sorting.

Introduces snapshotting of the hitCount, performed before sorting, so that value remains stable
 and the Comparator does not come up with conficting results. This is to make sure TimSort
 from JDK 7 does not throw exceptions.

This is a step towards JDK 7 compatibility
Unused imports.
Unignores TestIsolation and TestDoubleRecovery
Reduces the number of operations in MultiPaxosNetworkTest even further, trying to avoid potential timeouts
Ignores MultiPaxosNetworkTest pending investigation, to allow builds going through

Changes poms that require JDK jars to activate dependencies via profiles based on the jars existence

Previously it was activated based on OS name/family values instead. That created two dependencies, one
 on the OS name/family and the other on the file itself. This caused problems with the JDK6 to 7 transition
 for MacOS X, since the location of the JDK and libraries change between those two versions.
 The solution is to activate the dependency on the file's existence, since that is measureable on all
 JDK versions in an OS independent way.

Moves TestIsolation from enterprise to kernel and renames it, as well as the original TestIsolation

Moves the enterprise TestIsolation test to community, since it has no relation to HA or enterprise
 specific functionality. Also renames it to TestIsolationMultipleThreads to separate it from the
 other isolation test.
Renames the original TestIsolation to TestIsolationBasic since it tests the most rudimentary
 isolation guarantees.

Finally, Ignores the TestIsolationMultipleThreads since it is flaky (it was recently re-enabled).
