When system locale of the 32 bit Windows Vista is set to zh_TW, i.e., sun.jnu.encoding is equal to MS950, the test passed. Before only user locale was set to zh_TW.

Similar with 64 bit Windows Vista, when system locale is set to ja_JP, i.e., sun.jnu.encoding is equal to MS932, the test passed. Before only user locale was set to ja_JP.

So I'm closing this as not a defect...
