[jdk8u-ri] RFR: 8287132: Retire Runtime.runFinalizersOnExit so that it always throws UOE [v4]

[Iris Clark]

Hi, Bernd.

> How is this planned to float back to the updates project and the openjdk8 distributions which are out there?

After the MRel is delivered in Jul, the changes will be pushed to github.com/openjdk/jdk8u-dev which will be collecting changes for the October Security Release.  The changes will also be delivered into Oracle's Oct CPU release.

Thanks,
Iris

Hello,

Can I ask a stupid question? How is this planned to float back to the updates project and the openjdk8 distributions which are out there?

 I could imagine this has the potential to break existing programs if symbols get removed or if a function throws an exception. I would not expect such a removal in a version which is in maintenance. What am I understand here wrong? Why such maintenance releases to the 8u version anyway?

Gruss
Bernd

Spec changes in java.lang.{Runtime,Shutdown,System} align with CSR 8287133 and are as expected.
