RFAJ gives "Released MSG into wrong OMMPool" error message on the encoder.initialize call

in RFA

Simple OMM Posting consumer application; first POST works, in preparing the next post the call to encoder.initialize gives this error

com.reuters.rfa.omm.OMMException


: Released MSG into wrong OMMPool

at com.reuters.rfa.internal.rwf.RwfPool.release(Unknown Source)

at com.reuters.rfa.internal.rwf.RwfEncoder.clear(Unknown Source)

at com.reuters.rfa.internal.rwf.RwfEncoder.initialize(Unknown Source)

which I cannot find documented anywhere

    Finally tracked this down. I was releasing the POST message to the pool


    OMMMsg msg = (OMMMsg) encoder.getEncodedObject();

    ....

    ommpool.releaseMsg(msg);

    This then caused an exception the next time I tried to call


    encoder.initialize(OMMTypes.MSG, 1000);

    Hi @alan.bain

    Can you recreate this using one of our RFA Java examples e.g. com.reuters.rfa.example.omm.postingConsumer ?

    I have a vague recollection of another developer having a similar issue when they had acquired two OMMEncoders and accidentally transposed them in his code in one location.

    e.g. the above example has a _payloadOMMEncoder and _postOMMEncoder declared....

    It's definitely the same encoder & pool being used in both times. I don't have the separate _payload and _post encoders. Turning on IPC tracing I see the first message going out

    Can I get the source code to reproduce this problem in my environment?
