The code to pass double[], float[] or long[] was missing. I added it into
rev 422 of the JCC svn trunk [1].

I also just released JCC 1.9 to cheeseshop [2] with this and many other 
fixes since release 1.8:

  - fixed code generation for clone() broken by finalization proxy work
  - added 'union' to the list of reserved words
  - fixed castCheck() to work with finalization proxies
  - --compile no longer installs by default
  - fixed bug in __init__.cpp #include statements for package-less classes
  - fixed line ending bug on Windows
  - fixed multiple JCC-built extensions in same process problem
  - removed env argument from initVM() as it's redundant with the libjcc.dylib
  - reimplemented env->setClassPath() in terms of system URLClassLoader hack
  - added support for --include option
  - added 'NULL' to list of reserved words
  - added support for building shared libjcc library on Mac OS X and Linux
  - fixed bug with generating wrappers for abstract Enumeration implementations
  - added support for --install-dir and --use-distutils options
  - copy jcc runtime sources into extension source tree before compiling
  - added detection of invalid command line args
  - fixed double-free bug when passing in vmargs
  - added defines to enable building with MinGW (Bill Janssen)
  - added support for --bdist
  - added support for --compiler
  - fixed crasher on Windows with virtual JObject.weaken$()
  - fixed bug not checking return value from initVM()
  - fixed bug with findClass() not catching C++ exception when class not found
  - added missing code in parseArgs() to handle double[], float[] and long[]
