Subject [jira] Commented: (JDO-517) NPE on enhancement of classes with persistent properties
Date Tue, 18 Sep 2007 17:17:43 GMT

    [ https://issues.apache.org/jira/browse/JDO-517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12528453
] 

Andy Jefferson commented on JDO-517:
------------------------------------

Thx Michelle. Subsequent issue comes via
PCDSDepartment.java

public void setFundedEmps(Set employees) {
    this._fundedEmps = (_fundedEmps != null) ? new HashSet(employees) : null;
}

If the implementation passes in null (like it does when nulling non-PK fields) then the TCK
code tries to create HashSet(null) which ends in tears. All setters for collections/maps need
to allow for null being passed in.

> To reproduce, edit project.propeties, go to the end of the file, and edit out the comment
and blank lines so that the classes in the companyAnnotatedPC package are included in the
argument list to the enhancer.
