Hallo there,
I have an iPOJO (1.11.2) component using the @ServiceController annotation to
control the service publishing. Most of the time this works perfectly fine, but
occasionally I get an ArrayIndexOutOfBoundsException.
java.lang.ArrayIndexOutOfBoundsException: 4

org.apache.felix.ipojo.handlers.providedservice.ProvidedServiceHandler.__M_onSet(ProvidedServiceHandler.java:416)[83:org.apache.felix.ipojo:1.11.2]

at
org.apache.felix.ipojo.InstanceManager.onSet(InstanceManager.java:1401)[83:org.apache.felix.ipojo:1.11.2]
[..] (My own code following, where the service controller
boolean is manipulated)
Unfortunately I cannot share the consumer code nor reproduce the problem. I
looked into iPOJOs code to see what's going on [1], and there we have:
for (int j = 0; j < svc.getProperties().length; j++) {
Property prop = svc.getProperties()[j];
[...]
}
Which looks like a proper race condition to me, if svc.getProperties() changes
its value in the meantime because of missing synchronizations. I don't see any
synchronizations there, but I also don't know if they would be appropriate in
the first place.
Has anyone seen this failure? Any insights would be helpful.
Cheers,
Benjamin
