Bug 1302322

Description of problem:
When setting up encryption following https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Operations_Network/3.3/html/Admin_and_Config/configuring-ssl.html agent is not able to communicate with server and throws exception which is not very helpful. 

Version-Release number of selected component (if applicable):
JON3.3.5.ER01

How reproducible:
Always

Steps to Reproduce:
1. follow https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Operations_Network/3.3/html/Admin_and_Config/configuring-ssl.html to set up encryption

Actual results:
Agent is not communication with server and throws:
2016-01-27 07:42:39,728 ERROR [RHQ Agent Registration Thread] (enterprise.communications.command.client.ClientCommandSenderTask)- {ClientCommandSenderTask.send-failed}Failed to send command [Command: type=[remotepojo]; cmd-in-response=[false]; config=[{rhq.agent-name=fbr-jon335.bc.jonqe.lab.eng.bos.redhat.com, rhq.externalizable-strategy=AGENT, rhq.send-throttle=true}]; params=[{invocation=NameBasedInvocation[registerAgent], targetInterfaceName=org.rhq.core.clientapi.server.core.CoreServerService}]]. Cause: java.lang.reflect.InvocationTargetException:null -> java.lang.RuntimeException:null -> java.lang.NullPointerException:null. Cause: java.lang.reflect.InvocationTargetException

Expected results:
It should work.

Additional info:
There are 2 options:
a) add missing step to documentation
b) fix usage of default values

Problem is in agent-configuration.xml - to make it work it's necessary to uncomment keystore and truststore properties. This step is missing in documentation. This also means that default values are not used correctly.

This step is not necessary when using sslservlet.

To avoid confusion it should be the same for both sslservlet and sslsocket. Use default values or document that it's necessary to uncomment it in agent-configuration.xml
