> I am running some load tests agains an osgi app, which is running inside
> karaf 4.0.2, using Aries Blueprint and JPA (Hibernate) .
> The test is using multiple threads (10) to issue some random calls to the
> application.
> Sometimes, randomly, some of the call throwing NPE in TxInterceptor:
> {code:java}
> java.lang.NullPointerException
> at
> org.apache.aries.transaction.TxInterceptorImpl.postCallWithReturn(TxInterceptorImpl.java:101)[66:org.apache.aries.transaction.blueprint:1.1.1]
> at
> org.apache.aries.blueprint.proxy.SingleInterceptorCollaborator.postInvoke(SingleInterceptorCollaborator.java:75)[48:org.apache.aries.blueprint.core:1.4.4]
> at Proxy65968de8_a064_4203_9a53_5f0c8e536279.lockAll(Unknown
> Source)[:]
> {code}
> The NPE is thrown from "postCallWithReturn" and "postCallWithException" in
> following line:
> {code:java}
> token.getCoordination().end();
> {code}
> The "getCoordination()" call in above line is returning null.
> As I mentioned, it is happening from time to time. sometimes after 20 mins,
> sometimes after hours of test execution and it is happening in different
> transactional methods in different classes of the application.
