QualifierParameterHierarchy.getTop() does not return the correct top type

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Remove 
regex_qual_poly.RegexTypecheckVisitor.checkExceptionParameter(CatchTree)
2.  javacheck -processor 
org.checkerframework.checker.experimental.regex_qual_poly.RegexCheckerAdapter 
UnionTypes.java

UnionTypes.java:8: error: [exception.parameter.invalid] invalid type in catch 
argument.
        } catch (ArrayIndexOutOfBoundsException | StringIndexOutOfBoundsException exc) {
                                                                                  ^
  found   : QualParams(primary=RegexTop(),{})
  required: QualParams(primary=null,{__TOP__=null})

QualifierParameterHierarchy.getTop() returns 
QualParams(primary=null,{__TOP__=null}) when it should return  
QualParams(primary=RegexTop(),{})

Also a problem for the qual-param-poly TaintingChecker.
Remove: 
org.checkerframework.checker.experimental.tainting_qual_poly.TaintingCheckerAdap
ter.createSourceVisitor().new TypecheckVisitorAdapter() 
{...}.checkExceptionParameter(CatchTree)

javac -processor 
org.checkerframework.checker.experimental.tainting_qual_poly.TaintingCheckerAdap
ter SimpleLog.java
SimpleLog.java:8: error: [exception.parameter.invalid] invalid type in catch 
argument.
    } catch (Exception e) {
                       ^
  found   : QualParams(primary=TAINTED,{})
  required: QualParams(primary=null,{__TOP__=null})
1 error

I've fixed the interaction with the __TOP__ qualifier and removed the temporary 
code in the qual checkers.
