HashCode is invalid
-------------------
Key: QDOX-236
URL: https://jira.codehaus.org/browse/QDOX-236
Project: QDox
Issue Type: Bug
Components: Java API
Affects Versions: 1.12
Reporter: Lars K. W. Gohlke
at least in class JavaMethod
{code]
public int hashCode() {
int hashCode = name.hashCode();
if (returns != null) hashCode *= returns.hashCode();
hashCode *= getParameters().length;
return hashCode;
}
{code}
when parameter.set has zero length, hashcode turns to be zero as well
this affects usage in Maps
improvement would be to use:
http://commons.apache.org/lang/api-2.4/org/apache/commons/lang/builder/HashCodeBuilder.html
this could be also wrong in other classes
