NoSuchMethodException with default configuration (IsProbablyBinary.valueOf())

[ChuckNoxis]

Hi,
I got an Exception with the default configuration (http://law.di.unimi.it/software/bubing-docs/overview-summary.html#overview.description) on storeFilter and parseFilter.

Exception in thread "main" org.apache.commons.configuration.ConfigurationException: it.unimi.di.law.warc.filters.parser.ParseException: java.lang.RuntimeException: java.lang.NoSuchMethodException: it.unimi.di.law.warc.filters.IsProbablyBinary.valueOf()

When I remove the and not IsProbablyBinary() from storeFilter and parseFilter, the crawler starts and all is ok.

This might be an unwanted interaction with a new feature of the ObjectParser (default factory-method names). I'll look into it. Which version of dsiutils are you using?

[ChuckNoxis]

I'm using the "latest.release", so I suppose it's 2.4.2
I don't have this problem with this fork we have, https://github.com/guillaumepitel/BUbiNG (an old version of Bubing using the same version of dsiutils).

Could you try my last commit? I understand what is going on—I changed the convention for empty valueOf() factory methods (no argument instead of an empty string) and I forgot to adapt IsProbablyBinary. But the weird thing is that I cannot reproduce the problem.
