Subject Re: [jira] Commented: (HARMONY-33) java.nio.BufferOverflow exception while decoding ByteBuffer with UTF-16 charset
Date Fri, 05 May 2006 07:20:21 GMT
Andrew,

thanks for your comments. Looks like the bug in ICU is very simple and
I hope it will be fixed in the next ICU release. I just like to reopen
harmony-33 to correctly track issue status. At the moment it
reproduced with icu4jni3.4 , that's why I asked to reopen. As soon as
we get new version of ICU bug should be closed.

Thanks.
Vladimir.
