Many testcases from 142 regression workspace are failing with error Unrecognised os.arch == amd64 for all 1.4.2_xx on AMD64 Windows. Test4298156.java need to be updated in 142 workspace. This file is already updated in 150 workspace.

JDK Used for Testing:
1.4.2_11-b01

Error Thrown:
-------------
Failed. java.lang.RuntimeException: unrecognized system:os.arch == amd64 os.name == Windows 2003.

One among the failed testcases is 4298156. I check the same bug id in 150 regression workspace has been already updated with respect to 64bit os architecture.

All these testcases needs to be modified in workspace_142 to execute on AMD64.
