Not really, it's a limitation in Oracle's Java compiler. The compiler
could automatically partition the method into several smaller methods
when it hits the limit. Not doing this is a bit like having a C
compiler which refuses to allow declaring more than five local
variables because the target architecture has only got five
callee-saved registers.
