While migrating from oaw4 to mwe, I came across a change in the behaviour
of the org.eclipse.xpand2.output.JavaBeautifier class.

In order to be flexible within my different projects that all use the same
workflow, I am using some parameters to specify different options.

One of the parameters is the configuration file that has to be used by the

In oaw4, I achieved, that the default formatting behaviour should be used
by simply specifying an empty string as configuration file for the
In mwe, I would have to skip the entire attribute "configFile".
If I pass an empty string (or an invalid file name) to that attribute,
error messages occur and no formatting is done at all.

Viewing the source of JavaBeautifier, I see that the default values are
only set, if
* either the attribute is skipped
* or the file is empty

If the filename is en empty string or simply invalid, the class displays
error messages that the java files contain invalid java code.

In my opinion, the "invalid configuration file" behaviour should be
identical to the "no configuration file at all" behaviour.

I just want to ask, if this change in behaviour is intended or not.
(I for myself would prefer to have back the "old" one. ;-))

My "workaround" currently is, that I created a completely empty file I'm
using as reference each time I want the default behaviour.
