Subject [jira] [Created] (LUCENE-3939) ClassCastException thrown in the map(String,int,TermVectorOffsetInfo[],int[]) method in org.apache.lucene.index.SortedTermVectorMapper

ClassCastException thrown in the map(String,int,TermVectorOffsetInfo[],int[]) method in org.apache.lucene.index.SortedTermVectorMapper
--------------------------------------------------------------------------------------------------------------------------------------

                 Key: LUCENE-3939
                 URL: https://issues.apache.org/jira/browse/LUCENE-3939
             Project: Lucene - Java
          Issue Type: Bug
          Components: core/index
    Affects Versions: 3.5, 3.4, 3.1, 3.0.2
            Reporter: SHIN HWEI TAN


The method "map" in the "SortedTermVectorMapper" class does not check the parameter "term"
for the valid values. It throws ClassCastException when called with a invalid string for the
parameter "term" (i.e., "var3.map("*", (-1), null, null)"). The exception thrown is due to
an explict cast(i.e., casting the return value of termToTVE.get(term) to type "TermVectorEntry").


Suggested Fixes: Replace the beginning of the method body for the class "SortedTermVectorMapper"
by changing it like this:

public void map(String term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions)
{
	if(termToTVE.get(term) instanceof TermVectorEntry){
	  	TermVectorEntry entry = (TermVectorEntry) termToTVE.get(term);
 		...
	}
}
