exception when extracting text from pdf-file #123

Open FroggieFrog opened 6 years ago

FroggieFrog commented 6 years ago

I tried to use TikaOnDotNet, but it already fails in a very simple test-project (see attachment). Is there anything I can do to make it work?

Some infos: Os: Win 10 1803 Locale: de-de

The error message:

TikaOnDotNet.TextExtraction.TextExtractionException: Extraction of text from the file '...tikadotnet.pdf' failed. ---> TikaOnDotNet.TextExtraction.TextExtractionException: Extraction failed. ---> System.TypeInitializationException: Der Typeninitialisierer für "org.apache.tika.metadata.Metadata" hat eine Ausnahme verursacht. ---> System.InvalidCastException: Das Objekt des Typs "java.util.PropertyResourceBundle" kann nicht in Typ "sun.util.resources.OpenListResourceBundle" umgewandelt werden.

I think this a duplicate of #118. @chrisoverton91 Did you find a fix?
