ClassCastException on the same class when install my custom feature

Bug Medium Resolved Done Jie Han Jie Han Fri, 12 Jul 2019 06:02:26 +0000 Fri, 13 Sep 2019 16:01:30 +0000 Mon, 29 Jul 2019 08:11:01 +0000 4.0.3 3.0.11 blueprint 0 2 <p>Need to dive into how LeafCodecClassLoader works when a bundle which provides binding classes has been refreshed.</p> <p>I think this is a classloader issue — notable question is which class loader DataStorePropertiesContainer belongs to. I suspect blueprint here is retaining the old API, though cannot be sure.</p> <p><span class="image-wrap" style=""><img src="https://jira.opendaylight.org/secure/attachment/15300/15300_ClassCastException.PNG" style="border: 0px solid black" /></span><br/> There indeed exists two diffrent EquinoxClassLoaders as shown above.<br/> DataStorePropertiesContainer is from EquinoxClassLoader@20354 whreas the type of deserialized object is <br/> from EquinoxClassLoader@20355, futher more, the initial classloader is sort of EquinoxClassLoader@13154<br/> that is also different too.</p> <p> <span class="image-wrap" style=""><img src="https://jira.opendaylight.org/secure/attachment/15301/15301_OverView-ModuleInfoContext.png" style="border: 0px solid black" /></span> </p> <p>Well, loadClass() should not be loading any module infos, really. The loadClass() request should block until the schema for that particular class is available, by which time it should be registered there. I suspect current state of affairs is just a manifestation of the issues which <a href="https://jira.opendaylight.org/browse/MDSAL-392" title="Clean up BindingRuntimeContext instantiation" class="issue-link" data-issue-key="MDSAL-392"><del>MDSAL-392</del></a> is supposed to address.</p> <p>i.e. firing order in OSGi needs to ensure that when Bundle A is resolved, the adding event is either:</p> <ol> <li>propagated to mdsal-binding-dom-codec (as a new BindingCodecContext) before 'loadClass A' targeting from current generation of the bundle is ever possible, or</li> <li>it must eventually resolve after service re-injection (due to services changing)</li> </ol> <p>Goal 1) requires a framework-synchronous listener (I think) and also assigning mdsal-dom-schema-service-osgi and mdsal-binding-dom-codec-osgi start levels lower than anything else in ODL, so that they are started before anyone else.</p> <p>This fix may help the FrozenClass exceptions we see with Javassist, hence let's backport it to 3.0.x.</p> Relates MDSAL-466 Development Rank 0|i03oe7:
