Regarding javac, the patch to `Log.java` seems to be in a reasonable direction: the write is to the physical `System.out/err` which should be done(?) using the native encoding. The order of the changed lines should be fixed, so that the javadoc is kept above the `initWriters` method. (As a secondary comment, it maybe a matter of discussion on whether keeping the native encoding in a static field is warranted here, but I don't mind it much.)

Regarding JShell, I guess I need to try to find a way to reproduce for me, so that I can debug. AFAIK the main process does not read/write from/to the console using `System.in`/`System.out`, so encoding plays no real role for the console, but it plays role in the communication between the agent and the main process.
