Can  you give some details :
- which version of ant,
- which platform,
- a small sample of the build file,

a quick look at the code shows that this would happen if the buffer size set
in ChainReaderHelper is 0. But the default is 8192, I wonder in which
circumstances this buffer size gets set or reset to 0. Do you have any
custom tasks/custom filters/javascript in your build file ?
