Hi,
I'm using UIMA-AS in a single JVM process, with having the activemq broker, the
uima-as client and the as deployment in the same java process.
UimaAsynchronousEngine.sendAndReceiveCAS() is used to send and wait for the
processed CAS.
This setups works with fine with brokerURL "tcp://localhost:61616".
If I change the brokerURL to "vm://localhost?broker.persistent=false" I get
this NullPointerException on reply and after successful processing of the CAS.
java.lang.NullPointerException: null

If I use "vm://localhost?marshal=false&broker.persistent=false" as brokerURL,
there is a similar NPE before processing at
java.lang.NullPointerException: null

Both are due to empty dispatchers in
org.apache.uima.aae.spi.transport.vm.VmTransport for the temp reply queue.
Are these bugs and/or is there any way to avoid tcp/http brokerURL?
Thank you very much,
John
