Subject NullPointerException in rest MessageServlet when new message arrives
Date Sun, 23 Sep 2012 09:08:21 GMT
I am trying to add rest support to my activemq-5.6 based server. 
I added the MessageServlet and started a http get request to a topic, but
when the message is sent I receive this exception:

java.lang.NullPointerException: null
	at org.apache.catalina.connector.Request.setAttribute(Request.java:1559)

Any idea why this is happening ?
