Initial JDK 11 RFR of JDK-8173382: Add -source 11 and -target 11 to javac - Java Bug System & JDK-8193291: Add SourceVersion.RELEASE_11

[Paul Sandoz]

Hi Joe,

I would like to see the class file version increment [*] in the same patch (the unified repo makes this easier now).

Then we have everything in one changeset (except for any ctsym changes?) that can be easily templated when the next increment is required, since we will be doing this far more regularly from now on.

Are there any technical impediments as to why this would be problematic?

Thanks,
Paul.

[*] here is the increment to 54 http://hg.openjdk.java.net/jdk/jdk/rev/89829dd3cc54 <http://hg.openjdk.java.net/jdk/jdk/rev/89829dd3cc54>
