When creating a a RuleBasedAgent with the following code: org.drools.agent.RuleAgent.newRuleAgent(properties), having properties only the url property, the following stacktrace appears: 

java.io.IOException: Was unable to reach server.
	at org.drools.agent.URLScanner.hasChanged(URLScanner.java:155)
	at org.drools.agent.URLScanner.getChangeSet(URLScanner.java:119)
	at org.drools.agent.URLScanner.loadPackageChanges(URLScanner.java:96)
	at org.drools.agent.RuleAgent.checkForChanges(RuleAgent.java:410)
	at org.drools.agent.RuleAgent.refreshRuleBase(RuleAgent.java:362)
	at org.drools.agent.RuleAgent.configure(RuleAgent.java:347)
	at org.drools.agent.RuleAgent.init(RuleAgent.java:247)
	at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:187)
	at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:147)

followed by

 java.lang.NullPointerException
	at org.drools.agent.RuleAgent.refreshRuleBase(RuleAgent.java:363)
	at org.drools.agent.RuleAgent.configure(RuleAgent.java:347)
	at org.drools.agent.RuleAgent.init(RuleAgent.java:247)
	at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:187)
	at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:147)


That´s OK to throw the IOException, but the NullPointerException should not happen.
