Hi, Eric, I think I have the same problem.
I found out in latest MultiReader.java, the "SegmentInfos" is set to null.
public MultiReader(IndexReader[] subReaders) throws IOException {
super(subReaders.length == 0 ? null : subReaders[0].directory(),
null, false, subReaders);
}
However, segmentInfos are used in several places, causing NPEs.
For example, in IndexReader.acquireWriteLock(),
if (SegmentInfos.readCurrentVersion(directory) >
segmentInfos.getVersion())
{
So I think MultiReader.java need some adjustments.
