Bug 565417 - package com.sun.jdi is accessible from more than one moduleY20200813-1200

This patch switches compilation to Java 11 to consume "com.sun.jdi"
packages from JDK, but requires patch for jdt.debug which would remove
duplicated jdi packages contributed by jdt.debug.

This is required to avoid "The package com.sun.jdi is accessible from
more than one module" error, because jdt.debug ships own version of
"com.sun.jdi" packages, and this breaks compilation on Java 11.
