> JAXWS: Performance: Remove Synchronization in JAXBUtils
> -------------------------------------------------------
>
> Key: AXIS2-3302
> URL: https://issues.apache.org/jira/browse/AXIS2-3302
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: jaxws
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
>
> Problem:
> The following method(s) in JAXBUtils have an undesireable side effect:
> public static JAXBContext getJAXBContext(TreeSet<String> contextPackages, ...)
>
> On input, the contextPackages set contains package values.
> On output, the contextPackages set contains package values, but the invalid package values are removed.
> The contextPackages object is used by multiple threads. Currently we use some flawed synchronization logic to avoid ConcurrentModificationExceptions.
> Proposal:
> The above side effect is really a legacy artifact of the development of JAXBUtils. Axis2 does not depend on the side effect.
> I am removing the side effect (and thus removing unnecessary synchronization)
> After the change:
> On input, the contextPackages set contains package values.
> On output, the contextPackages set contains the same package values.
> No one should be depending on this side effect, so this should be a safe change.
> I will commit a fix later today.
