Description

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.
