Issue

• If a rule compares String fields which consist of many digits, it may be wrongly evaluated.

For example, the following test doesn't fire the rule

import org.drools.compiler.Person;
rule R1
  when
    $p : Person( name < "90201304122000000000000017" )
  then
end

ksession.insert( new Person( "90201304122000000000000015", 38 ) );
