I'm still investigating, but is anybody else seeing problems signing a large file (not huge, just 200k or so) with an enveloped signature? I'm seeing crashes in the c14n transform step where it tries to flush the new UnsyncBufferedOutputStream class, which tells the internal digester to update itself and that fails because it thinks the input is too short.
Since that class is only 5 weeks old, I'm suspicious. I'm still working on testing an older library version to see if that works on my code. -- Scott
