Mock destinations in camel roots cause memory leaks when sending a lot of messages

1)Install the bundle with the following root: <?xml version= "1.0" encoding= "UTF-8" ?> <blueprint xmlns= "http: //www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi= "http: //www.w3.org/2001/XMLSchema-instance" xmlns:cm= "http: //aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0" xmlns:jaxws= "http: //cxf.apache.org/blueprint/jaxws" xmlns:cxf= "http: //cxf.apache.org/blueprint/core" xmlns:camel= "http: //camel.apache.org/schema/blueprint" xmlns:camelcxf= "http: //camel.apache.org/schema/blueprint/cxf" xsi:schemaLocation=" http: //www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd http: //cxf.apache.org/blueprint/jaxws http://cxf.apache.org/schemas/blueprint/jaxws.xsd http: //cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd "> <bean id= "stringAggregationStrategy" class= "org.jboss.fuse.qa.performance.StringAggregationStrategy" /> <camelContext id= "blueprintContext" trace= " false " xmlns= "http: //camel.apache.org/schema/blueprint" > <route> <from uri= "jetty:http: //0.0.0.0:8888/splitter" /> <split streaming= " true " > <tokenize token= "note" xml= " true " /> <to uri= "direct:a" /> </split> </route> <route> <from uri= "direct:a" /> <setHeader headerName= "id" > <simple>1</simple> </setHeader> <transform> <simple> "Hello ${body}" </simple> </transform> <to uri= "direct:aggregate" /> </route> <route> <from uri= "direct:aggregate" /> <aggregate strategyRef= "stringAggregationStrategy" completionSize= "2" > <correlationExpression> <simple>header.id</simple> </correlationExpression> <to uri= "mock:a" /> </aggregate> </route> </camelContext> </blueprint> 2) Send 15000 request with sy-camel-route-splitter-aggregator.xml to http://0.0.0.0:8888/splitter . OutOfMemoryError: GC overhead limit exceeded If replace <to uri="mock:a"/> with <transform> <simple> "from aggregate" </simple> </transform> no exception occurs. The message for sending is attached as well as heapdump.
