Error on Export to FeatureHouse

[nickat]

While exporting an annotated Project of BerkeleyDB JE 4.1.7 to FeautreHouse I get the following error:

An internal error occurred during: "Exporting CIDE -> FeatureHouse (Java)".
org.eclipse.jdt.core.dom.EnumDeclaration cannot be cast to org.eclipse.jdt.core.dom.TypeDeclaration

Stack trace:

The error can be reproduced:

1. Download BerkeleyDB JE 4.1.7
2. Export the Project to FeatureHouse
   The error occurs even if no annotations were made at all.
