Changes

  • JMS/Routing Swiftlet: TCP No Delay is now configurable (in prior releases is was enabled by default). An attribute "use-tcp-no-delay" has been added to the network listener/connector definition of these Swiftlets.
  • JMS Client: It is now possible to change the thread priority of client-side thread pools via system property "swiftmq.pool.session.priority" and "swiftmq.pool.connection.priority".
  • JMS Client: JMS 1.1 dependency has been removed [prior released were using BytesMessage.getBodyLength()]. So the client part can now be used in JMS 1.0.2 based app servers without prepending the SwiftMQ jms.jar to the app server's classpath.
  • JMS Client: TCP No Delay is now configurable via system property "swiftmq.tcp.no.delay" (in prior releases is was enabled by default).
  • SMQP/SMQPR Protocol: Request timeout is now configurable via system property "swiftmq.request.timeout"

Bugfixes

  • JMS Resource Adapter: Removed internal version dependencies.
  • JDBC Store Swiftlet: Column "expirationtime" in the create sql scripts have column type INTEGER (must be BIGINT).
  • Routing Swiftlet: ConcurrentModificationException thrown during disconnect. Fixed missing synchronize.
  • Routing Swiftlet: Fail on XA prepare does not close the connection.
  • JMS Client: Connect request stuck (SMQPVersionRequest sent but no reply received).
  • JMS Client: NullPointerException when adding a new subscriber on a topic which was qualified with a router name (forbidden).
  • Message Selector: Negative Long values were not selected.
  • JNDI Object Factory: Connection factories of version 5.1.0 are not created.
