[11u] OpenJDK 11.0.3 post GA fixes JDK-8210739 and JDK-8203679

[Langer, Christoph]

Hi,

we had already discovered JDK-8210739: Calling JSpinner's setFont with null throws NullPointerException [1], [2] as being fixed in 11.0.3-oracle b31, which is probably a post 11.0.3 GA build of Oracle.

Another bug has been brought to our attention that had had been fixed by Oracle in an 11.0.2 post GA build b31: JDK-8210483: AssertionError in DeferredAttr at setOverloadKind caused by JDK-8203679 [3]. The issue with that bug is that it was never pushed to the jdk11u repository. Oracle has only fixed this in their internal repos. Unfortunately, it fell through all the filters because these believed it was already part of the open 11.0.2 code base and hence we didn't include it in OpenJDK 11.0.3. It has, however, been backported to 11.0.4, that is, it was pushed to jdk11u-dev.

So, both bugs (JDK-8210739 and JDK-8203679) will be missing in the imminent jdk-11.0.3+7, respectively jdk-11.0.3-ga pushes.

I suggest we push both of these fixes (which apply cleanly and are pretty local to their area) to jdk11u after Andrew (Hughes) has pushed the CPU changes and after that add a jdk-11.0.3+8 tag. Then, downstream vendors can chose to create another update based on the new tag if they need to deliver binary versions that include these fixes. I'll also run these fixes through our SAP test system but I don't expect any regressions.

Any opinions?

I've flagged both bugs with jdk11u-critical-request. If I get maintainer approval by Andrew (Haley), I would do this.

Thanks
Christoph
