> Key: LUCENE-1519

> Project: Lucene - Java
> Issue Type: Bug

> Hi
> We are getting an exception while optimize. We are getting this exception
> "mergeFields produced an invalid result: docCount is 385282378 but fdx file
> size is 3082259028; now aborting this merge to prevent index corruption"
>
> I have checked the code for class SegmentMerger.java and found this check
> ***********************************************************************************************************************************************************************
> if (4+docCount*8 != fdxFileLength)
> // This is most likely a bug in Sun JRE 1.6.0_04/_05;
> // we detect that the bug has struck, here, and
> // throw an exception to prevent the corruption from
> // entering the index. See LUCENE-1282 for
> // details.
> throw new RuntimeException("mergeFields produced an invalid result:
> docCount is " + docCount + " but fdx file size is " + fdxFileLength + "; now
> aborting this merge to prevent index corruption");
> }
> ***********************************************************************************************************************************************************************
> In our case docCount is 385282378 and fdxFileLength size is 3082259028, even
> though 4+385282378*8 is equal to 3082259028, the above code will not work
> because number 3082259028 is out of int range. So type of variable docCount
> needs to be changed to long
> I have written a small test for this
> ************************************************************************************************************************************************************************
> public class SegmentMergerTest {
> public static void main(String[] args) {
> int docCount = 385282378;
> long fdxFileLength = 3082259028L;
> if(4+docCount*8 != fdxFileLength)
> System.out.println("No Match" + (4+docCount*8));
> else
> System.out.println("Match" + (4+docCount*8));
> }
> }
> ************************************************************************************************************************************************************************
> Above test will print No Match but if you change the data type of docCount to
> long, it will print Match
> Can you please advise us if this issue will be fixed in next release?
> Regards
