> Project: Qpid JMS
> Issue Type: Improvement
> Components: qpid-jms-client
> Affects Versions: 0.37.0
> Reporter: Francesco Nigro
> Priority: Trivial
> Fix For: 0.38.0
>
>
> JmsBytesMessage::initializeReading() creates DataInputStream that allocates
> several byte[] and char[] even when no methods need them.
> Using directly the underline ByteBufInputStream would reduce the amount of
> garbage created while reducing the indirections needed to hit the underline
> ByteBuf that hold the data.
