Hello all;

I've noticed that I can't seem to use ctrl-\ to get a stack dump of long running java processes (mostly the jdk javac compile) using the new build. Instead I get something like: make: *** [jdk-only] Quit (core dumped) mike at samuel:~/code/jdk/jdk9-dev$ ./jdk9-dev/common/bin/logger.sh: line 44: 44468 Quit (core dumped) ( exec 3>&1; ( "$@" 2>&1 1>&3; echo ?>"? > "?>"RCDIR/rc" ) | tee -a $LOGFILE 1>&2; exec 3>&- ) 44469 (core dumped) | tee -a $LOGFILE cat: /tmp/jdk-build-logger.tmp.LiOGwf/rc: No such file or directory

I don't see how make and all the intervening shells could know to pass the signal through to the JVM process. ??

I can use jps from another shell just fine. Is this behaviour expected? At minimum it looks like the cleanup is incomplete.
