Mandy, Thread.dumpStack should generate the stacktrace elements then capture System.err into a local var and lock it while writing the output. That would be compatible with what was done before.

Any feedback on the proposed API is appreciated. Mandy P.S. webrev of the current implementation: http://cr.openjdk.java.net/~mchung/jdk9/jep259/webrev.00/
