> This line of code causes the exception in JBIDestinationOutputStream:
> ByteArrayOutputStream baos = (ByteArrayOutputStream)getOut();
> Guillaume Nodet has given me an untested patch that he thought might fix the
> issue. I have written a unittest which performs a write with a large amount
> of data and then attempts to close the stream. Without the attached patch
> applied, the unit test will fail, but with it applied, the test passes.
> The CachedOutputStream class is really a haven for this sort of error since
> it seems that subclasses and invokers of this class seem to be assuming that
> the getOut() method will magically return the correct type of class that they
> need, but there are 3 types that could possibly be returned. I would also
> suggest that to eliminate future errors, that this class use a ByteBuffer
> internally instead of dynamically manipulating OutputStreams (this would also
> make more sense if this class is meant to cache the data to be written). It
> would be much easier to use one type consistently in this class rather than
> several. The only problem I can see which this approach (which is why I
> haven't tried to implement it) is the constructor that allows a
> PipedInputStream. If you guys are interested, I can implement a ByteBuffer
> internally, change getOut() to return a concrete OutputStream class (to
> eliminate ClassCastExceptions, or it could return the DataBuffer) and then
> write the DataBuffer to a stream when the data is to be committed. This
> would be easy depending on the PipedInputStream in the constructor. Using a
> directbuffer would probably make it pretty fast as well.
