QPID-6770: Prevent chains of DirectByteBuffers forming when slicing the
thread-local cached buffer
> Prevent chains of DirectByteBuffers forming when slicing the thread's cached
> buffer
> -----------------------------------------------------------------------------------
>
> Key: QPID-6770
> URL: https://issues.apache.org/jira/browse/QPID-6770
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
>
> The QBB has a per thread cached DirectByteBuffer. Callers requiring a buffer
> are served slices of this buffer. The algorithm currently takes a slice of
> the buffer for the caller, then takes a second slice to represent the bytes
> that remain unused in the buffer and discards the original references. This
> approach has the unfortunate consequence that a chain of ByteBuffers forms as
> each DirectByteBuffer slice references its parent via its attachment field.
> The following posting describes the issue:
