Wei Yin Teo updated XMLBEANS-209:
---------------------------------
Attachment: saver.patch
This happen when a char that is replaced is near the end of the circular buffer, e.g. \
'&' at i = 16381, _in = 16382, _buf.length = 16384, dCch = 4, replacement = '&'. \
System.arraycopy is called with destination index at 'i+dCch' = 16385 which is \
greater than the buffer length.
Special care must be taken care when the replacement will wrap around the buffer.
Please see the attach diff for the fixes.

> Key: XMLBEANS-209
> URL: http://issues.apache.org/jira/browse/XMLBEANS-209
> Project: XMLBeans
> Type: Bug
> Versions: Version 2
> Environment: Java2 RE 1.4 and Java2 RE 5.0
> Reporter: Koyama Hiroshi
> Attachments: saver.patch
>
> Stacktrace is as follows.
> java.lang.ArrayIndexOutOfBoundsException
> at java.lang.System.arraycopy(Native Method)
> at org.apache.xmlbeans.impl.store.Saver$TextSaver.replace(Saver.java:1438)
> at org.apache.xmlbeans.impl.store.Saver$TextSaver.entitizeContent(Saver.java:1269)
> (snip)
> I checked each variables.
> 1438: System.arraycopy( _buf, i, _buf, i + dCch, _in - i ); // i:16358 \
> _in:16381 dcCh:4 _buf.length:16384 I think _buf has not enough size.
> So, I changed source as follows.
> 1438: if (_buf.length < _in+dCch+_in-i) i = resize( dCch, i);
> 1439: System.arraycopy( _buf, i, _buf, i + dCch, _in - i );
> This is not good patch, but I can save xml data.
> regards.
