>
> When using the JMS transport sender for sending messages to external broker
> it creates InitialContext per message. This is actually unnecessary since we
> can cache and use the same intialContext., and also some brokers behave
> strangely when re-creating the initialContext. This patch cache the
> InitalContext using the EPR as the key. User can specify to use caching using
> the property "transport.jms.CacheInitialContext" set to true. Synchronization
> has done as required since creating InitialContext is not thread safe and
> also JNDI look up.
> User has to define an Initial Context definition in the JMSTransport sender
> configuration as follows.
> <transportSender name="jms" class="org.apache.axis2.transport.jms.JMSSender">
> <parameter name="default" locked="false">
> <parameter name="java.naming.factory.initial"
> locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
> <parameter name="java.naming.provider.url"
> locked="false">tcp://localhost:61616</parameter>
> <parameter name="transport.jms.ConnectionFactoryJNDIName"
