ByteBuffer.wrap(byte[] n, int offset, int length) calls clear() on the wrapped
NIO buffer
-----------------------------------------------------------------------------------------
Key: DIRMINA-146
URL: http://issues.apache.org/jira/browse/DIRMINA-146
Project: Directory MINA
Type: Bug
Versions: 0.9
Reporter: Niklas Therning
Fix For: 0.9.1
clear() is called on the underlying NIO buffer wrapping the byte array. The
consequence is that the position is set to 0 and the limit is set to capacity
(the length of the wrapped array). Since this method should behave exactly as
the NIO ByteBuffer equivalent the position should be set to offset and the
limit should be set to offset+length.
Whenever an existing NIO ByteBuffer is wrapped in a MINA ByteBuffer the NIO
buffer is cleared. That may not always be desirable. I suggest that the call to
clear() is removed from DefaultByteBuffer.init(). That would take care of the
bug described above. If the user wishes to wrap an NIO buffer she would have to
make sure it is cleared if that is desired.
NOTE: This isn't a problem in MINA 0.8. clear() isn't called on the wrapped NIO
buffer in DefaultByteBuffer.init(). Does anyone know why this was introduced in
0.9?
