[Bug 63111] Javac task CreateProcess Error 206 on windows

--- Comment #3 from Fergal Gavin <fe...@ie.ibm.com> ---
Hi folks,

Has anything changed internally between ANT 1.10.6 and ANT 1.10.7 with regards
to the <javac> target and the limit for the associated generated command line.

We have observed within out project:

 - same location for the "ANT" installation.
 - same location for the Java source being compiled.

When we run the same build script target to compile the source for a specific
directory, the build is successful using ANT 1.10.6 (and earlier versions
including the 1.9.x versions) but falls over using the specific 1.10.7 version
(see error below).

Any ideas on what could be causing this with regards to the possible changes
introduced between those two versions of ANT?

Thanks,

Fergal.
