Checkstyle Custom rule fails to instantiate

package softquatrachecks;

import com.puppycrawl.tools.checkstyle.api.Check;
import com.puppycrawl.tools.checkstyle.api.DetailAST;
import com.puppycrawl.tools.checkstyle.api.FullIdent;
import com.puppycrawl.tools.checkstyle.api.TokenTypes;
import com.puppycrawl.tools.checkstyle.checks.CheckUtils;

/**
 * 
 * 
 * This package provides the custom checks that were required outside 
 * of the standard checks provided
 * 
 */
public class LoggerAttrCheck extends Check
{
	 /**
     * 
     * Indicator 7: Logging Mechanisms
     * 
     * The Logger must be declared as a static final class attribute
     * 
     */
    @Override
    public int[] getDefaultTokens()
    {
        return new int[] {
            TokenTypes.VARIABLE_DEF
        };
    }

    @Override
    public void visitToken(DetailAST aAST)
    {
		
    	if(aAST.getType()==TokenTypes.VARIABLE_DEF)
    	     visitVariableDef(aAST);

    }
    /**
     * Checks type of given variable.
     * @param aAST variable to check.
     */
    private void visitVariableDef(DetailAST aAST)
    {
        checkVariableDefn(aAST);
    }

    /**
     * 
     * Checks variable to see if its a Logger and static final
     *      * @param aAST node to check.
     */
    private void checkVariableDefn(DetailAST aAST)
    {
        final DetailAST type = aAST.findFirstToken(TokenTypes.TYPE);
        final FullIdent ident = CheckUtils.createFullType(type);
        if ((ident.getText().equals("Logger"))) {
        
if((!aAST.branchContains(TokenTypes.FINAL))||(!aAST.branchContains(TokenTypes.LITERAL_STATIC)))
			{
   			 log(type.getLineNo(), type.getColumnNo(),
     		        "Logger not defined as static final class attribute",
type.getText());
			}    
        }
    }

}
When the rule is processed I get the message:
"Unable to create Checker: cannot initialize module TreeWalker - Unable to
instantiate LoggerAttr"

Now my checkstyle_packages.xml file in che checkstyle-5.5 folder is  :
<?xml version="1.0" encoding="UTF-8"?>

    <!DOCTYPE checkstyle-packages PUBLIC
    &quot;-//Puppy Crawl//DTD Package Names 1.0//EN&quot;
    &quot;http://www.puppycrawl.com/dtds/packages_1_0.dtd&quot;>

<checkstyle-packages>
  <package name="softquatrachecks"/>
</checkstyle-packages>

Any Ideas folks
