Subject Re: [jira] Commented: (HARMONY-6408) [classlib][luni]OutputStreamWriterTest got java.nio.BufferOverflowException
Date Mon, 21 Dec 2009 11:40:29 GMT
Hi Regis,

I rebuild the luni native code in trunk, and found that its behavior
same as java6 now, I don't know what happened.
Sorry for confusing.

Now the problem is simple, I think we got GB2312 as the default encode
on my machine, I will do more investigation.
