[jira] [Created] (CXF-6354) NullPointer exception in
Sanjeet Karamchandani created CXF-6354:
------------------------------------------
Summary: NullPointer exception in
Key: CXF-6354
URL: https://issues.apache.org/jira/browse/CXF-6354
Project: CXF
Issue Type: Bug
Affects Versions: 2.7.2
Reporter: Sanjeet Karamchandani
Priority: Critical
I have a requirement where I need to move a webservice call to a seperate thread so that I could retry if it doesn't complete within a time limit. To achieve I moved my webservice call to a futuretask and in my main thread I am doing a task.get(timeout). A webservice call that is normally completed in few miliseconds doesn't complete even after 10 mins if I move it into a seperate thread call.
Is there a problem with CXF. I am getting a NullPointer exception around the cxf.endpoint.ClientImpl.onMessage() call. Stacktrace at the end.
I am including the code thats causing problems only when I move the call in a seperate thread.
@Override
public IRuleSet loadRuleSet(String ruleSetName) throws RulesEngineException {
IRuleSet ruleSet=null;
ExecutorService executor = Executors.newFixedThreadPool(1);
for (IRuleSetLoader ruleSetLoader : loaders) {
try {
FutureTask<IRuleSet> task = new FutureTask<IRuleSet>(new LoaderTask(ruleSetLoader, ruleSetName));
executor.submit(task);
long timeout=30;
try{
ruleSet = task.get(timeout, TimeUnit.SECONDS);
}catch(Exception e) {
LOGGER.info("202::Exception", e);
}
// if I uncomment the below call and comment the above task submit it works perfectly fine.
//ruleSet = ruleSetLoader.loadRuleSet(ruleSetName);
if (ruleSet != null){
return ruleSet;
}else {
ruleSet = ruleSetLoader.loadRuleSet(ruleSetName);
}
} catch (Exception e) {
LOGGER.info("Failed to load rule set " + ruleSetName + " using ruleSetLoader:" + ruleSetLoader.getClass(), e);
}
}
throw new RulesEngineException("Unable to load RuleSet " + ruleSetName);
}
private final static class LoaderTask implements Callable<IRuleSet> {
private final IRuleSetLoader ruleSetLoader;
private final String ruleSetName;
private LoaderTask(IRuleSetLoader ruleSetLoader, String ruleSetName) {
this.ruleSetLoader = ruleSetLoader;
this.ruleSetName = ruleSetName;
}
@Override
public IRuleSet call() throws Exception {
LOGGER.info("Starting task.");
IRuleSet ruleSet=null;
try {
ruleSet = ruleSetLoader.loadRuleSet(ruleSetName);
} catch (Exception e) {
LOGGER.info("101::Exception encountered", e);
}
return ruleSet;
}
}
