commit 28ca752e0536a22e3f830f971fff5e3ef49174a6
Author: Jan Palus <atler at pld-linux.org>

    follow jdk >= 10 and enable AssumeMP by default
    
    let's make jdk8 independent of glibc implementation details at the cost
    of minor deviation from a standard behavior. workaround with
    _JAVA_OPTIONS still to be kept for possibly "broken" jdk8 used to build
    new version with toggled default.
    
    see https://github.com/openjdk/jdk11u/commit/fd93a046840bd5ff51bdbc4586319440b0041f1c
