need ideas for how to name incremental jdk builds to be findable by /usr/libexec/java_home

[Stephen Bannasch]

I tried naming a openjdk built today from the jdk70-dev forest 1.7.0-2012_02_24.jdk -- but the jdk isn't displayed in The "Java 
Preferences" application.  Presumably because the initial designation '1.7.0' is shadowed because of the existing 1.7.0.jdk.

$ /usr/libexec/java_home -v 1.7 -V

Matching Java Virtual Machines (2):
     1.7.0, x86_64:	"OpenJDK 7"	~/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
     1.7.0, x86_64:	"OpenJDK 7"	~/Library/Java/JavaVirtualMachines/1.7.0-2012_02_24.jdk/Contents/Home
