Kevin Sutter commented on OPENJPA-2240:
---------------------------------------
I have been trying to reproduce the situation with no luck. Granted, I don't
have the hyperjaxb and the associated XML libraries. But, from your
description, it sounded like I should be able to reproduce the VerifyError with
an extra helper getter method that called a utility method passing in a .class
as the first parameter. Just something to complicate the getter method just
enough to screw up the StackMapTables. But, I have had no luck. As an
example, here's what I added to a simple Entity class:
@Basic
@Column(name = "DATATIMEITEM")
@Temporal(TemporalType.TIMESTAMP)
public Date getDataTimeItem() {
// return
XmlAdapterUtils.unmarshall(XMLGregorianCalendarAsDateTime.class,
this.getDataTime());
return unmarshall(XMLGregorianCalendar.class, this.getDateField());
}
private Date unmarshall(Class<XMLGregorianCalendar> class1, Date
dateField2) {
// TODO Auto-generated method stub
return dateField2;
}
I tried this with Java6sr9 (my current default), Java6sr10 (your current Java),
and Java7. No luck with reproducing. If you can help with narrowing down the
scenario with a simpler testcase, or maybe provide the Entity classes and
needed libraries to reproduce it, I'm very interested in tracking down this
problem. Thanks.

> ------------------------------------------------------
>
> Key: OPENJPA-2240
> URL: https://issues.apache.org/jira/browse/OPENJPA-2240
> Project: OpenJPA
> Issue Type: Bug
> Components: Enhance
> Affects Versions: 2.2.0
> Environment: IBM-JDK, SUN-JDK
> Reporter: Piotr Klimczak
> Priority: Critical
> Labels: enhancement, hyperjaxb3, jpa, stubs, xsd
>
> 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.
