Emitting java bytecode?

Hello! Would be possible for GHC to emit Java bytecode? There seems to be some code in GHC's sources (in ghc/compiler/javaGen/) suggesting that it was anticipated. I suppose most of the work would be in making a java RTS and libraries. I am mainly interested in making GHC more portable. Haskell is a great application programming language, but there are some concerns about portability of applications. Perhaps I shouldn't be looking at java bytecode for a solution... Is it possible that a C-- backend will make GHC more portable? Best regards, Tomasz
