> looking for more informative exception messages when parsing invalid Ruta
> script
> When using Ruta in a non-Workbench setup (in my case, Maven), I don't manage
> to catch Ruta script errors in a meaningful way. Here is an example:
> "aaa\." -> MyAnnotation; // fails because of escaped dot
> The thrown error is quite uninformative:
> java.lang.ArrayIndexOutOfBoundsException: -1
> at
> org.apache.uima.ruta.parser.RutaParser.emitErrorMessage(RutaParser.java:365)
> at
> org.apache.uima.ruta.parser.RutaParser.reportError(RutaParser.java:386)
> at
> org.antlr.runtime.BaseRecognizer.recoverFromMismatchedToken(BaseRecognizer.java:603)
> at org.antlr.runtime.BaseRecognizer.match(BaseRecognizer.java:115)
> at
> org.apache.uima.ruta.parser.RutaParser.file_input(RutaParser.java:680)
> at
> org.apache.uima.ruta.engine.RutaEngine.loadScript(RutaEngine.java:1058)
> at
> org.apache.uima.ruta.engine.RutaEngine.initializeScript(RutaEngine.java:743)
> ...
> Here is the code to reproduce:
> https://github.com/renaud/annotate_ruta_example/tree/ruta_error_message
> However, if I paste that script line in the Ruta Workbench, it nicely
> underlines it in red at the exact location, and even says "Mismatched input".
> How do I achieve the same programatically (from Java)?
