My guess is that the script contains carriage returns.
To look for them, use 'od'. To remove them, use 'd2u'
or 'dos2unix' if you've got them, else 'tr'.

This:
  /cygdrive/c/jdk1.6.0_16<cr>
  /bin/java
displays thus:
  /bin/java/c/jdk1.6.0_16<cr>

$echo "/cygdrive/c/jdk1.6.0_16\r/bin/java"
/bin/java/c/jdk1.6.0_16

$echo "/cygdrive/c/jdk1.6.0_16\r/bin/java" |od -t a
