[jira] Created: (OPENJPA-336) PCEnhancer throws an NPE when run
with DefaultAccessType=PROPERTY on a MappedSuperclass
PCEnhancer throws an NPE when run with DefaultAccessType=PROPERTY on a MappedSuperclass
---------------------------------------------------------------------------------------
Key: OPENJPA-336
URL: https://issues.apache.org/jira/browse/OPENJPA-336
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.0.0
Reporter: Marc Prud'hommeaux
With the following class:
package test;
import javax.persistence.*;
@MappedSuperclass public abstract class MyMappedSuperclass {
public void doSometing() { }
}
Running the PCEnhancer with DefaultAccessType=PROPERTY as follows:
java org.apache.openjpa.enhance.PCEnhancer -MetaDataFactory 'jpa(DefaultAccessType=PROPERTY)' -Log DefaultLevel=TRACE test.MyMappedSuperclass
Causes an NPE:
Exception in thread "main" <openjpa-1.0.0-r420667:568385 nonfatal general error> org.apache.openjpa.util.GeneralException: null

[jira] Commented: (OPENJPA-336) PCEnhancer throws an NPE when run
with DefaultAccessType=PROPERTY on a MappedSuperclass
Posted by "Chad Patras (JIRA)" <ji...@apache.org>.

Chad Patras commented on OPENJPA-336:
-------------------------------------
The same issue occurs when a mapped class has no field of the same data type matching the property accessor. For example.
public class AWrapper
{
private StringBuffer myString = new StringBuffer();
public void setMyString(String string) {
myString.setLength(0);
myString.append(string);
}
public String getMyString() {
return myString.toString();
}
}
