Kelly,

I'm assuming the intention is to have a launcher such as Eclipse parse
the "jdk.release" file and look for the value of "jdk.vm.cfg.files",
and then parse that value. Is this a list of files separated by the
path.separator or some other string? Does the separator need to be
another property? Finally the launcher would parse each (jvm.cfg) file
and look for one of the JVMs (server, client, zero, cacao, hotspot,
etc.).

There seems to be a mismatch between the email's "jdk.java.version"
and webrev's "jdk.version" in Release.gmk line 521:
 508 # Common way to emit a line into $(JDK_INFO_FILE)
 509 define jdk-info-file # name value
 510 $(PRINTF) "jdk.%s = %s\n" $1 $2 >> $@
                    ^
... snip ...
 519 $(JDK_INFO_FILE): FRC
 520         $(prep-target)
 521         $(call jdk-info-file, "version",      "$(THIS_JDK_VERSION)")
                                    ^
