Dumping "Java -Version" to variable

[Jason]

I'm looking at creating an Extension Attribute that grabs the output of running "java -version". However, if no java is installed then i get the output "No Java runtime present, requesting install." That part is fine, but then it opens a dialog and tries to download java.

Is there any way to get the output from terminal, but NOT have it request to install? (or another way to get the same version information this would report on)?

Thanks

I use this one to get Java version or tell me if it's not installed:

I have a similar one as well, but it only lists the version for plug-ins. There could still be Java on the machine even if it's not in the Internet Plug-Ins folder. The results from "java -version" should be a pointer to the version of java that the system uses, but it has that annoying prompt...
