String.split/toUpperCase/toLowerCase/replaceAll do not work

[ogrammer]

EDIT: I found that this same error also affects toUpperCase and toLowerCase.
EDIT: I found that a similar error affects replaceAll

String string = "A;b;c";
String[] strings = string.split(";");
for (String s : strings) Console.console().log(s);
Console.console().log(string.toUpperCase());
Console.console().log(string.toLowerCase());

I guess this is the root cause, and the wrapping exception message was
de.mirkosertic.bytecoder.ssa.ControlFlowProcessingException: Error processing CFG for sun/util/locale/provider/LocaleProviderAdapter.forType, right?

Its an exception handler with PHI values that cannot be resolved correctly. I thought I fixed that many moons ago, but here is another corner case I missed. It is damn hard to get JVM Exception handling right.

About the Reflection API usages in the compiler log: is is not a warning or an error. It is meant to inform the user about certain Reflection API usages. The used classes are not automatically resolved, as some cases are not always needed, as seen by Latin1 Character encodings vs, whole UTF vs. generated code size.

[ogrammer]

Yes indeed that was the message, I thought it was unnecessary so I left it out. How about providing an option to disable to Reflection API usage logger? It's pretty unnecessary to me.

Merged to master. All other RegEx related issues will be resolved by #269.
