But is your context defined multiple times? in different virtual hosts
maybe?

This means that it is loaded in two separate class loaders which would point
to the same context being defined multiple times in server.xml.
note that contexts are auto-loaded, so if you defined contextA as path=""
docbase="/contextA", it will be loaded twice, once for "" and the default
loading of "/contextA".
