Hi *,
we're seeing the exception below happening randomly under load. It stems
from
org/apache/camel/impl/DefaultUnitOfWork.java:
public RouteContext popRouteContext() {
if (routeContextStack.isEmpty()) {
return null;
}
return routeContextStack.pop();
}
It seems the stack gets empty inbetween the empty-check and the pop
operation.
What about doing something like this, to prevent this inconsistency:
public RouteContext popRouteContext() {
synchronized (routeContextStack) {
if (routeContextStack.isEmpty()) {
return null;
}
return routeContextStack.pop();
}
}
should i file a JIRA issue for this?
cheers,
Matthias
