java.lang.NoSuchMethodError: java.util.Properties.load(Ljava/io/Reader;)V

Hi Michal,

I get the following exception with the single jar version of libSBOL on my Mac.

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: java.util.Properties.load(Ljava/io/Reader;)V

The issue appears to be that java.util.Properties.load was introduce in Java 6, and I'm using Java 5. We have found that we have lots of compatibility issues when we use things that only work in Java 6, so we target Java 5 in our builds. Is it possible for you to rewrite this to be Java 5 compatible?

Thanks,

Chris

f/u from chris:

the exception that I got did not appear when we used the separate jar files. It only appeared when we used the jar file that combined all the files (0.3). Does this make any sense to you?

Chris:
tried 0.4, and have same issue:

and
FYI: it works fine for Java 1.6. This is a Java 1.5 issue which unfortunately is the version I have on my computer.
