Subject [jira] [Resolved] (OPENJPA-1778) Improved error information for unenhanced classes.
Date Wed, 06 Jul 2011 21:39:16 GMT


Rick Curtis resolved OPENJPA-1778.

       Resolution: Duplicate
    Fix Version/s: 2.2.0

I ran a testcase with unenhanced classes on 2.1.x and here is the output:

172  test_2  WARN   [main] openjpa.Enhance - Unenhanced classes were detected even though
the enhancer has ran. Ensure that the EntityManagerFactory is created prior to creating any
172  test_2  WARN   [main] openjpa.Enhance - This configuration disallows runtime optimization,
but the following listed types were not enhanced at build time or at class load time with
a javaagent: "

I believe this issue has already been resolved. Please reopen if you'd like to see some other
information in the message.

> The exception message issued by openjpa 2.0 for the use of an unenhanced class is not
as useful as the message issued by the 1.x versions.  In 2.0, the following message is received:
> <openjpa-2.0.0-r422266:935683 nonfatal user error> org.apache.openjpa.persistence.ArgumentException:
Attempt to cast instance "org.apache.sample.entities.Book@97781f" to PersistenceCapable failed.
Ensure that it has been enhanced.
> FailedObject: org.apache.sample.entities.Book@97781f
> While the same application run using openjpa 1.x gives this message:  
> <openjpa-1.2.1-r752877:753278 fatal user error> org.apache.openjpa.persistence.ArgumentException:
No metadata was found for type "class org.apache.sample.entities.Book". The class does not
appear in the list of persistent types: [org.apache.geronimo.sample.entities.Book].
> The 2.0 message no longer points to the persistence.xml definition as the potential source
of error.  It should give some possible solutions to "Ensure that is has been enhanced". 
Perhaps something like "Ensure that the class is included in the list of persistent types
or enhanced as part of the application build".
