Thank you for reply.
I have installed the 64bit viesion ( not exist 32 ver. at oracle site).
I can't find same post.
Then, I have runed that code groovy and ScriptMaster at same Mac.
System.getProperty("java.home”)
from groovyConsole
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre
from ScriptMaster
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
I think that
ScriprMaster plugin used "/Library/Java/Home/bin/java"
