JDK Version: 1.5.0-beta-b09, b14
Java HotSpot(TM) Client VM (build 1.5.0-beta-b14, mixed mode)

Problems:

I have attached a sample code which passed in 1.4.2-b28 and 1.5.0-beta-b08, but it fails 1.5.0-beta-b09 and later builds, currently testing on 1.5.0-beta-b14.

The code is to test SystemFlavorMap method: addUnencodedNativeForFlavor(DataFlavor flav, String nat) with valid natives and DataFlavors. This stress test will define numerous mappings of valid String natives and DataFlavors. The mappings will be verified by examining that all entries are present.

Seems the mapping was changed in 1.5.0-b09 and later builds.
