Tor Tuga, here's more information on the volatile problem. Spring just deal
with it in its latest release:
http://opensource.atlassian.com/projects/spring/browse/SPR-3304
> Detect illegal overloaded JavaBeans properties methods (e.g. setters)
> ---------------------------------------------------------------------
>
> Key: IBATIS-128
> URL: https://issues.apache.org/jira/browse/IBATIS-128
> Project: iBatis for Java
> Issue Type: Improvement
> Components: SQL Maps
> Affects Versions: 2.0.8
> Environment: iBatis 2.0.7
> Reporter: Jerome Lacoste
> Assigned To: Jeff Butler
> Priority: Minor
> Fix For: 2.2.0
>
>
> ClassInfo keys setters by their names.
> private void addMethods(Class cls) {
> Method[] methods = cls.getMethods();
> for (int i = 0; i < methods.length; i++) {
> String name = methods[i].getName();
> if (name.startsWith("set") && name.length() > 3) {
> if (methods[i].getParameterTypes().length == 1) {
> name = dropCase(name);
> --> setMethods.put(name, methods[i]);
> setTypes.put(name, methods[i].getParameterTypes()[0]);
> }
> See
> http://cvs.sourceforge.net/viewcvs.py/ibatisdb/ibatis-dbl-2/src/com/ibatis/common/beans/ClassInfo.java?rev=1.8&view=markup
> So if you overload a method in your bean, you never know which one is going
> to be stored last in the map.
> With:
> public void setFeatureIDs(Set featureIDs) {
> this.featureIDs = featureIDs;
> }
> public void setFeatureIDs(List featureIDs) {
> this.featureIDs = new TreeSet(featureIDs);
> }
> I end up with the following error:
> Error setting property 'setFeatureIDs(java.util.Set=[2] $Proxy4 implements
> interface java.util.List)' of 'Part-20021'. Cause:
> java.lang.IllegalArgumentException: argument type mismatch Caused by:
> java.lang.IllegalArgumentException: argument type mismatch];
> See issue IBATIS-127 for debugging
