Similar exception would be thrown when trying to apply @XmlType to a property complaining org.eclipse.jpt.jaxb.core.internal.resource.java.source.SourceField cannot be cast to org.eclipse.jpt.jaxb.core.resource.java.JavaResourceAbstractType.

Reproducible: Always

Correction of the last paragraph in the bug description:

Similar exception would be thrown when trying to apply @XmlType to a property
complaining org.eclipse.jpt.jaxb.core.internal.resource.java.source.SourceMethod cannot be cast to
org.eclipse.jpt.jaxb.core.resource.java.JavaResourceAbstractType.

Verified in Build I-3.4.0-20110826171354 

Verified when you add @XmlType to a field that no CastClassException appears in the error log.  See the link to view test steps for verification.
