Not sure about the new deprecation warnings for the old WB classes .. might that not itself trigger some failures? If not then I don't see how the deprecation warnings help with transitioning to the new WB class? the deprecation warnings (hopefully) will help people not to forget that they should use the new WB class in new tests. If the test passes it is unlikely people will actually notice these in the jtr file - and even if they see them they may just ignore them thinking they are similar to all the security manager warnings that we ignore. But as long as it does no harm. Cheers, David Thanks, -- Igor Hi Jie, Shall we also update the copyright year like test/lib/sun/hotspot/cpuinfo/CPUInfo.java? we most certainly shall, just pushed the commit that updates the copyright years in the touched files.
