Subject Re: cvschangelog crashes with NullPointerException
Date Wed, 01 Sep 2004 10:20:46 GMT
Hello Benno,
this does look like a bug in ant, because this happens in the java code.
Other possibility : an environment problem, like the JDK on your PC not
knowing what the default locale for calendar is ?
