I have had a problem with jvc compiling complex code (a matrix diagonalisation converted from Fortran) where it threw an internal compiler error. And the Lark problem where I have to compile with jvc rather than javac. I imagine that it's a good idea in general to run code through as many compilers as possible and I make sure that mine works with jvc and javac. [...] >The validation implementation is pretty naive.
