580782: Enforce Java 11 compatibility for compiler.

Java 9 and above expose a '-release' parameter that tells the compiler
to enforce API and binary (classfile) compatibility with the given
version. This is a stronger guard than the '-source' and '-target'
options. If any code uses language features or API's that don't
exist in the given version, the compiler will emit an error and fail
hard.

For Mylyn Docs, enforce Java 11 compatibility.
