java.lang.ClassCastException: org.apache.lucene.codecs.MappingMultiDocsEnum
cannot be cast to org.apache.lucene.index.DocsAndPositionsEnum

-------------------------------------------------------------
I test lucene on shenandoah with big memory + bigdata(128G, 1.2T).
http://openjdk.java.net/jeps/189
http://icedtea.classpath.org/hg/shenandoah/
It throws above exception.
I see the luence code, I think the exception is ok.
Because org.apache.lucene.codecs.MappingMultiDocsEnum is not instanceof org.apache.lucene.index.DocsAndPositionsEnum.
