Include only tools.jar as "system jar", not the entire jre/../lib folder

Hello,

I have a folder structure as below:

• root
  • jre
    • JRE files (“java.home” points to this)
  • lib
    • my jars

The current logic within JREUtils is seeing all my jars within this “lib” folder as “system jars”:

            if (javaHomeFile.getName().equals("jre")) {
                // Handle jre/../lib/tools.jar
                final File parent = javaHomeFile.getParentFile();
                if (parent != null) {
                    final File parentLibFile = new File(parent, "lib");
                    addJREPath(parentLibFile, jrePathsSet);
                }
            }

Would it be possible - and sensible - to only regard “tools.jar” as a system jar, instead of the entire “lib” folder?

This was tested with version 3.1.0.

@lukehutch looks good. I tested "lib:", "lib:my.jar", "lib:prefix*"; it took me longer, because I had a problem with the log (with .verbose()) not being generated at all. Turned to be an out-of-memory issue on my part; obviously all this lib scanning needs to be done carefully.

Thank you for your support, and I’ll just take advantage of the opportunity to tell you that this is an awesome little project - good luck with all!
