RFR: JDK-8210731 PropertiesParser does not produce reproducible output

Thu Sep 13 22:20:52 UTC 2018

The file make/langtools/tools/propertiesparser/PropertiesParser.java 
b/make/langtools/tools/propertiesparser/PropertiesParser.java is used to 
convert .properties files into .java files as part of the gensrc step.

However, due to it's use of creating it's output directly from HashMaps, 
it's not guaranteed to be stable, and is causing spurios differences in 
our cmp-baseline builds.
