hm ,works fine on two machines, but failed on a third one.
all run with the same version of jdk, ant and the same OS

the error message =
"Error reading project file: ... " occurs only in
ProjectHelper and ProjectHelperImpl classes in ant 1.6.5
and comes from the catch block of an InputStream

my last tests with

<taskdef resource="de/.../.../ant/antlib.xml">
   <classpath path="path/tothejar/that/didnt/work/>
</taskdef>

and the same jar that didn't work with
<taskdef resource="de/.../.../ant/antlib.xml"/>
and %ANT_HOME%/lib/xxx.jar worked like a charm on the production
machine with a small test script that loads some selfwritten
tasks ?!?!?!?

completely baffled ... but i'm not allowed to try it again
with the real production scripts and
<taskdef resource="de/.../.../ant/antlib.xml"/>
combined with %ANT_HOME%/lib/thejarthatdidntworklateley.jar

is there a difference between jar loading
when
a) taskdef with classpath path="..."
b) taskdef with jar in %ANT_HOME%/lib

why does the same jar file fails only on one machine, is there
a kind of jdk configuration when dealing with ImputStreams
or loading of jar files ?!

it did run fine on all machines before adding the new task
and extending the antlib.xml

i know it's not an ant bug but a java problem, as the ProjectHelper* 
classes only use a simple InputStream, but i thought someone on that 
list could help, already came across the same problem.
