system reserved property names

System.getProperties [1] returns all of the "current" system properties. Is there a way to get a list of the system reserved properties such as "java.version" and etc.? Would anyone know? [1]http://docs.oracle.com/javase/6/docs/api/java/lang/System.html#getProperties%28%29 Thanks, Joe

If I don't get a chance to revisit the whole UUID optimization patch soon I will see what I can do about breaking it up further and maybe just do the no-copy String constructor by itself. Mike On Apr 17 2013, at 20:29 , Martin Buchholz wrote: > To be concrete, here's a proposed toString method

Re: RFR: String.join(), StringJoiner additions

To be concrete, here's a proposed toString method : http://cr.openjdk.java.net/~martin/webrevs/openjdk8/toString/ which is pretty good as it stands, but even better once it gets to use the no-copy String constructor.
