[Bug] JavaCC throws an Error [sf#65] #10

Closed patrickwestphal closed 9 years ago

patrickwestphal commented 9 years ago

Reported by kurzum on 2010-08-19 13:17 UTC in: public class TokenMgrError extends Error This eror is sometimes not caught and transformed to the checked Exception. So effectively, if an Application uses try{} catch (ParseException e) {} the error can still run through and wreck the application

[ERROR] org.dllearner.parser.TokenMgrError: Lexical error at line 1, column 8. Encountered: "a" (97), after : "F" [ERROR] at org.dllearner.parser.KBParserTokenManager.getNextToken(parser:KBParserTokenManager.java):1309) [ERROR] at org.dllearner.parser.KBParser.jj_ntk(parser:KBParser.java):1219) [ERROR] at org.dllearner.parser.KBParser.Concept(parser:KBParser.java):425) [ERROR] at org.dllearner.parser.KBParser.TBoxEquiv(parser:KBParser.java):267) [ERROR] at org.dllearner.parser.KBParser.parseConcept(parser:KBParser.java):30) [ERROR] at org.nlp2rdf.navigator.server.store.LogicalRelationStrategy.add(LogicalRelationStrategy.java:132) [ERROR] at org.nlp2rdf.navigator.server.store.LogicalRelationStrategy.update(LogicalRelationStrategy.java:154) [ERROR] at org.nlp2rdf.navigator.server.store.Store.saveConcept(Store.java:39)

The problem description is not clear. A ParseException is thrown if something wasn't correct and the parser was created by JavaCC. If an application catches the exception and ignores it, it is its own fault.

I'll close this issue because I don't see any choice to solve it in the DL-Learner framework.
