for-loop
> Problem: 
> Using method cfg.getMethods() is not as safe as it appears. The field varList is filled
with all available configuration options. The evaluation of the options is order dependent
to field varList (especially for the option "target-player" ). The order of methods returned
by cgf.getMethods() is JVM, Classloader, and memory dependent. Sometimes the order is loaded
differently as expected and the "target-player" option is evaluated after SDK-swcs are collected
for the compilation which results in incorrect compiler initialisation, incorrect error reports,
and failing compilations.
> About Method getMethods:
> http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getMethods%28%29
> The relevant part: 
> ".... The elements in the array returned are not sorted and are not in any particular
order..... "
> This problem is serious if the compiler should be embedded into an IDE like FDT. The
Classloaders in Eclipse behaves slightly different to the default Classloaders. 
> The same problem occured with the latest Adobe Flex SDK Action Script Compiler 2.0. Since
Adobe's cycle of development is very slow we decided to solve this problem within FDT by simply
sorting the varList field according to a working default order.
