[rules-users] DrlParser with "Unknown error while parsing..."

[Wolfgang Laun]

Additional information:
This was executed in an Eclipse project R, with other projects in the same
workspace.
The DRL file contains an experimental rule which happens to contain patterns

that refer to classes which are not in project R, but in some other project.

The FileReader is set up with an absolute path, but the succsessful building
uses
   kBuilder.add( ResourceFactory.newFileResource( "...some.drl" ),
ResourceType.DRL );

After omitting the "experimental rule", parser.parse(...) succeeds.
