Re: Illegal UTF8 String in Constant Pool

Hi,

You need to reference an assembly that contains org.jboss.logging.BasicLogger when compiling XNIO (or include the jar). There is a bug in IKVM's dynamic class loading fall back mechanism that causes the class to be truncated when loaded dynamically, but you shouldn't be loading it dynamically.

Regards,
Jeroen
