Hi Dave,
It still does not address the NPE issue.  If an alias is  NULL.  What should be the behavior?

  public String getTypeForAlias(String alias) {
    String type = TYPE_ALIASES.get(alias);
    if (type != null) {
      return type;
    }
    type = TYPE_ALIASES.get(alias.toLowerCase()) // NPE STILL HERE;
    if (type == null) {
      type = alias;
    }
    //populate for future use
    TYPE_ALIASES.put(alias, type);
    return type;
  }

Very good question. I guess we should return null in this case.

I'll fix that

Dave

public String getTypeForAlias(String alias) {
	String type = TYPE_ALIASES.get(alias);
	if (type != null) {
	return type;
	}
	type = TYPE_ALIASES.get(alias.toLowerCase()) // NPE STILL HERE;
	if (type == null) {
	type = alias;
	}
	//populate for future use
	TYPE_ALIASES.put(alias, type);
	return type;
	}
