Using JPA inheritance with solr search causes compile errors due to name conflicts

The following is an excerpt from a script that produces the problem:

/* ====== Asset ====== */
entity jpa --class com.bigcorp.domain.assets.Asset --inheritanceType SINGLE_TABLE --testAutomatically
field string --fieldName name --sizeMax 60
/* ====== FixedAsset ====== */
entity jpa --class com.bigcorp.domain.assets.FixedAsset --extends com.lyniad.domain.assets.Asset --inheritanceType SINGLE_TABLE --testAutomatically
solr setup
solr all

At build time the resulting error is:
[ERROR] D:\EclipseWorkspace\SAMPLE\src\main\java\com\bigcorp\domain\assets\FixedAsset_Roo_SolrSearch.aj:105:0::0 Ca
nnot override the final method from Asset

where line 105 is:
public static final SolrServer FixedAsset.solrServer()

{ SolrServer _solrServer = new FixedAsset().solrServer; if (_solrServer == null) throw new IllegalStateException("Solr server has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?)"); return _solrServer; }

which conflicts the the same method define in the superclass, Asset:
public static final SolrServer Asset.solrServer()

{ SolrServer _solrServer = new Asset().solrServer; if (_solrServer == null) throw new IllegalStateException("Solr server has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?)"); return _solrServer; }
