Java 12: several internal classes have been removed

[cyrille-artho]

The following five classes no longer exist:

JavaLangInvokeAccess
JavaNetURLAccess
JavaObjectInputFilterAccess
JavaObjectInputStreamAccess
JavaUtilJarAccess

They were used as an "unofficial API" in the past. We will have to find replacements for the functionality that they provided.

Is this solved ?

No, this work was not completed. We have resolved many issues about Java 11, and that work is currently on branch `java-10-gradle` (soon to be renamed to `java-11`).

I am getting some error like this when trying to build using older java versions:

Java 11 bytecode is completely incompatible with Java 8. So you have to compile and run code from branches `java-10-gradle` or `java-12` with the right Java version. The former can be compiled and used with Java 11, the latter with Java 12 (although many tests still fail in the latter, and a few in the former).
