I've solved that problem for my own purposes a few months ago, by just
hacking a bit at java.c, so it can read it's command line arguments from a
file, using the usual @file syntax (that Javac already supports, but
implemented in Java). Even enabled env. var. substitutions a la Ant, using
the ${env.VARNAME} syntax. You can even *set* env. var. within that command
line file, which is something I needed to debug JNI code from within Visual
Studio, to set the Path (using env. vars. to be location independent) to
find dependents of native libraries (since SUN apparently can't use
LoadLibraryEx as Steve L. pointed out). That hacked up java.exe (Windows
HACK only) find the right JDK as specified in the registry, which is just
normal behavior (didn't have to code that).Never had a problem since... --DD -----Original Message----- From: Ignacio J.

Hence this patch, the Launcher in addition to create a UCL, adds a system property ant.class.path and starts ant's Main.. i've modified ant Path type to add this property to the classpath like it's done with java.class.path ( this property is readonly ).., and if using build.sysclasspath=only, this property contents are added in addition to java.class.path.. Comments are welcomed.. Saludos, Ignacio J.
