> Greetings,
> This fixes the issue seen in testing when accessing an oop as part of unloading (introduced with [JDK-8266936](https://bugs.openjdk.java.net/browse/JDK-8266936)).
> Instead, oop accesses will be done outside of unloading and the result, i.e the codesource attribute, will be cached and reused in the FinalizerEntry.
> Testing: in progress
> Thanks

> PS one effect of this is that classes that unload before they have allocated anything will not have a codesource attribute. This can be fixed by letting classes register with the table as part of class loading, instead of during allocation. I will follow-up with a separate change for that.
