SDK's Launch4J hangs on Windows .exe generation

After enabling Windows EXE generation in my project (as well as Linux), I was 
finding that clean/rebuild was taking forever. 

Finally after several hours, and with the aid of jconsole to find out where the 
hang might be happening, I eventually traced the problem to Launch4J's 
"Validator" class.

This was seemed to be stuck in Java's regular expression classes when executing 
Validator.checkOptions(). 

It turned out that was caused by me adding the following to my "Run" options in 
the SDK. I use Java Logging extensively, and had added this option to get some 
tidier output.

-Djava.util.logging.SimpleFormatter.format='%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS 
%4$s %2$s %5$s%6$s%n'

This gets passed to Launch4 which then has trouble with the regular expressons 
that validates and goes into a mad loop! I am guess some escaping needs to 
happen somewhere.

This happens on latest JME3 SDK on Ubuntu Mint 15 64bit (with both OpenJDK7 and 
Oracle7)
