Description

Hello,

I am using Velocity (velocity-dep-1.3.1) to generate e-mails on the fly with a
Java program.
Velocity is initialized with a custom properties file, which however currently
does not hold any velocity-relevant information. The property file resides on
an NFS share.
Everything used to work fine for several weeks but I am now getting
nullpointer exceptions from velocity when initializing it with the properties
file. This behaviour seemingly started, after I mirrored the harddisc on
which the properties files were on, to a new drive. The NFS export on that
machine has not changed at all since it was an exact mirror. Other programs
have not differed in behaviour, so this is definitely odd.
Even more strange to me is that when initializing Velocity with it's own
properties file (which means I am not passing any file as an argument to
init() ), I still get the nullpointer exception.

When copying the (Eclipse) project to my local disc and debug the program from
there, everything works as expected.

Thanks for your help.
