Field "class" not recognized in some constructs
-----------------------------------------------

                 Key: JBRULES-2995
                 URL: https://issues.jboss.org/browse/JBRULES-2995
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.2.0.CR1
            Reporter: Wolfgang Laun
            Assignee: Mark Proctor


Given this simple type:

declare Foo
    clazz : Class
end

and this rule:

rule yyy
when
       $f: Foo( $cl: clazz == ( java.lang.String.class ) )
 ###   $f: Foo( $cl: clazz, eval( $f.getClazz().equals( java.lang.String.class ) ) )
 ###   $f: Foo( $cl: clazz == java.lang.String.class )
then
    System.out.println( "--- got a " + $cl );
end

Only the first vyariant is accepted by the DRL parser. Other forms are
rebuked with, e.g.:

Unable to Analyse Expression  $f.getClazz().equals( java.lang.String.class ) :
[Error: Failed to compile: 2 compilation error(s): 
 - (1,24) unable to resolve method using strict-mode: ex10.Foo.java()
 - (1,24) unqualified type in strict mode for: java]
[Near : {... $f.getClazz().equals( java.lang.String.class ) ....}]
                                   ^
[Line: 1, Column: 24] : [Rule name='yyy']


Note the incorrect line number!
