[Sablevm-developer] Re: Running Ant? - update

[David <db...@cs...>]

Hi Etienne,

I fixed the exception bug but I still cannot get it to build.  I get the
error:
    ...
    [javac] Compiling 209 source files to
    /home/david/sablecc/sablecc-2.18.0/classes

    BUILD FAILED
    file:/home/david/sablecc/sablecc-2.18.0/build.xml:173: IO error
    scanning directory /home/david/sablecc/sablecc-2.18.0/classes

Any clue of what could cause that error?


About the bug fixed:

This is a bug in classpath unless the JVM spec is unclear.

Method.invoke(Object o, Object[] args) takes an Object[] for the
arguments.  Primitive must be wrapped.

Ant passes a Boolean[] as the args which is assignable to
Object[].  However, the classpath do this for primitive saying it
simplifies the VM:
boolean[] wrapper =3D new boolean[1];
wrapper[0] =3D ((Boolean) args[i]).booleanValue();
args[i] =3D wrapper;

but this last statement throws a ArrayStoreException since
boolean[] is not assignable to Boolean (it is however assignable to
type Object).

I have included a patch that should fix that first problem.
