Description

When creating a Tomcat servlet in the same JVM as Broker-J (tested with 8.0.2 and  8.0.6 on JDK8 due to external limitations), exceptions like attached occur. Tried to change the broker configuration in virtualhostnodes.virtualHostInitialConfiguration (taken from an example)

"virtualHostInitialConfiguration" : "{\"type\":\"BDB\",\"nodeAutoCreationPolicies\":[

{\"pattern\":\".*\",\"createdOnPublish\":\"true\",\"createdOnConsume\":\"true\",\"nodeType\":\"queue\"}

]}"

so that nodeAutoCreationPolicies contains something like \"attributes\":{} but this does not change the behavior. Unfortunately, the documentation does not give much explanation about automatic creation of virtual host nodes, the format, the pattern, etc.
