[RogerRiggs]

Given that the code has been that way for a long time, did you check that both paths work as intended and that tests exist for both paths?

[naotoj]

No, I did not check. I simply removed the true && as it is logically correct. There's a test specifying IBM964 in sun.nio.cs.TestIBMBugs.java, but not sure it tests both paths or not.
