Subject [jira] Updated: (HARMONY-6408) [classlib][luni]OutputStreamWriterTest got java.nio.BufferOverflowException
Date Tue, 22 Dec 2009 06:17:18 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-6408?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ray Chen updated HARMONY-6408:
------------------------------

    Attachment: Harmony-6408.diff

In the patch, I do three things:

1. Mapping 936 to GBK instead of GB2312 according to Windows Control Panel->Regional and
Language options, which is as same as RI do.

2. Fix one bug in GBK encoding

3. Fix one bug in GB2312 encoding, both of them should minus bbRemaining by one after putting
one byte into the buffer.

I have ran the nio, nio_char and luni test, no regression.

> In OutputStreamWriter's constructor using the default character encoding, on my machine,
it is GB2312. 
> If I set the encoder to "ISO8859_1" the test passed.
> So I think most of the members from China will got this error.
