Camel Property Placeholder - prop prefix not working in threadpool

1. Create a properties file "redhatexample.cfg" in the ${fuse_home}/etc folder with the following content: camel.test = Test thread.pool.keepalivetime = 60 thread.pool.maxpoolsize = 50 thread.pool.maxqueuesize = -1 thread.pool.poolsize = 20 thread.pool.rejectedpolicy = Abort stop= true 2. Create a "camel-context.xml" file in the ${fuse_home}/deploy folder with the following content: <?xml version= "1.0" encoding= "UTF-8" ?> <blueprint xmlns= "http: //www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:cxf= "http: //camel.apache.org/schema/blueprint/cxf" xmlns:xsi= "http: //www.w3.org/2001/XMLSchema-instance" xmlns:cm= "http: //aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0" xmlns:prop= "http: //camel.apache.org/schema/placeholder" xsi:schemaLocation= " http: //www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd http://camel.apache.org/schema/blueprint https://camel.apache.org/schema/blueprint/camel-blueprint.xsd" > <cm:property-placeholder id= "redhatexample" persistent-id= "redhatexample" update-strategy= "reload" /> <camelContext id= "example-context" xmlns= "http: //camel.apache.org/schema/blueprint" ><threadPoolProfile defaultProfile= " false " id= "getstatementinformation-pool" keepAliveTime= "{{thread.pool.keepalivetime}}" maxPoolSize= "{{thread.pool.maxpoolsize}}" maxQueueSize= "{{thread.pool.maxqueuesize}}" poolSize= "{{thread.pool.poolsize}}" prop:rejectedPolicy= "thread.pool.rejectedpolicy" /> <route id= "_example" > <from uri= "timer: //foo?fixedRate= true &amp;period=60000" /> <log id= "_log1" message= "Hello Camel: {{camel.test}}" /> </route> </camelContext> </blueprint> 3.
