Description

For certain combinations of document text and RuleElementLiteral in the script, method getAnnotation of class RutaLiteralMatcher throws a NullPointerException.  This seems to be the case whenever the used string is a postfix or infix of a word in the document, but itself doesn't occur.

Example

Script

 

DECLARE testType;
"est" {-> testType};
"est te"{-> testType};

Document

 

test test
