Subject [jira] [Commented] (OPENJPA-2240) JVMVRFY012 when using openjpa together with hyperjaxb3
Date Thu, 30 Aug 2012 08:17:07 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13444783#comment-13444783
] 

Piotr Klimczak commented on OPENJPA-2240:
-----------------------------------------

I am using maven 3.0.4.
I have reuploaded the project with one small fix- added spring-context dep. to jaxb plugin
which fixes possible ClassNotFoundException during stubs generation.

According to outputDirectory- yes, it is not docummented, but it works in older of maven and
is extremely helpful. Maybe a should (2.0.2 for example). In newer version 2.2+ there is a
generatedSourcesDirectory which is doing same thing as outputDirectory in older versions.
So you can comment this line if you want or change it to "generatedSourcesDirectory" (if you
are using newer compiler plugin), as it is responsible only for overriding the output directory
of entities metamodel sources, to let them be easily accessible by eclipse (in target/jaxws
as all other stubs).

Greetings,

> We are facing a problem with class enhancing generated by hyperjaxb3.
> "Caused by: java.lang.VerifyError: JVMVRFY012 stack shape inconsistent; class=foo/Bar,
metoda=pcgetDataTimeItem()Ljava/util/Date;, pc=7"
> The problem occurs on every usage of non JPA compatible type like XMLGregorianCalendar.
> For those types, the hyperjaxb3 plugin creates a kind of "proxy" setter/getter that uses
JPA capable type.
> Example of such proxy getter/setter:
> <code>
>         @Basic
>         @Column(name = "DATATIMEITEM")
>         @Temporal(TemporalType.TIMESTAMP)
>         public Date getDataTimeItem() {
>             return XmlAdapterUtils.unmarshall(XMLGregorianCalendarAsDateTime.class, this.getDataTime());
>         }
> </code>
> then the XmlAdapterUtils.unmarshall looks like:
> <code>
> 	public static <ValueType, BoundType> BoundType unmarshall(
> 			Class<? extends XmlAdapter<ValueType, BoundType>> xmlAdapterClass,
> 			ValueType v) {
> 		try {
> 			final XmlAdapter<ValueType, BoundType> xmlAdapter = getXmlAdapter(xmlAdapterClass);
> 			return xmlAdapter.unmarshal(v);
> 		} catch (Exception ex) {
> 			throw new RuntimeException(ex);
> 		}
> 	}
> </code>
> I have found that the problem occurs only because of the type of XmlAdapterUtils.unmarshall
method. The problem is that it's 1st type is a "Class". Changing the 1st type from Class type
to any other like Object solves the problem but it is not a solution.
> I think the problem is somewhere in serp project as after the enhancment process of classes
containing non JPA capable XSD types, each call of that class generates the JVMVRFY012 exception-
even during junit tests.
> Please note, that this bug is a blocker for my project.
