[jira] Created: (SM-1926) Statistics Service throws NPE with
DynamicEndpoints
Statistics Service throws NPE with DynamicEndpoints
---------------------------------------------------
Key: SM-1926
URL: https://issues.apache.org/activemq/browse/SM-1926
Project: ServiceMix
Issue Type: Bug
Components: servicemix-core
Affects Versions: 3.3.1
Reporter: Mark Ford
Priority: Minor
I am seeing NPE's in the console when using dynamic endpoints with the HttpComponent.
The stacktraces don't seem to impact the message exchanges. One workaround is to simply disable the service in conf/servicemix.xml. It would be easy to patch the code to avoid the NPE but I'm not sure whether the dynamic endpoints should be included in the stats and if so why the StatsService doesn't pick up on their registration.

[jira] Resolved: (SM-1926) Statistics Service throws NPE with
DynamicEndpoints
Posted by "Freeman Fang (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/activemq/browse/SM-1926?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Freeman Fang resolved SM-1926.
------------------------------
Resolution: Fixed
Fix Version/s: 3.3.2
As generally we use dynamic endpoints on the fly, so Statistics Service should just skip dynamic endpoint.
I will add Null check to avoid the NPE
commit fix
