Hi ,
I am getting strange error with queue when our applications write objects to
VM queue. Occasionally I am seeing below error. It is strange that we can
clearly see in the error message below that queue size value match. Any idea
why it is failing?
Caused by: java.lang.IllegalArgumentException: Cannot use existing queue
vm://FixTransform-BARX-Queue as the existing queue size 500000 does not
match given queue size 500000

Below is the code snippet that throws IllegalArgumentException when
comparing queue size. I do not understand how queue size do not match for
below conditional statement when 500000 is equal to 500000 in the above
statement. Is there some kind of data corruption here that some threads do
not get correct value for ref.getSize()?
SedaComponent.java
...
if (size != null && ref.getSize() != size) {
// there is already a queue, so make sure the size matches
throw new IllegalArgumentException("Cannot use existing
queue " + key + " as the existing queue size "
+ (ref.getSize() != null ? ref.getSize() :
Integer.MAX_VALUE) + " does not match given queue size " + size);
}
....
VM component name used in our application
"vm:FixTransform-BARX-Queue?size=500000&timeout=1000000&concurrentConsumers=5"
Kind regards,
