> Hi,
> When indexing large data sets with ByteBuffersDirectory, an exception like
> the below is thrown:
> Caused by: java.lang.IllegalArgumentException: cannot write negative vLong
> (got: -4294888321)
> at org.apache.lucene.store.DataOutput.writeVLong(DataOutput.java:225)

> {{The exception is caused by an integer overflow while calling
> getFilePointer() in Lucene50PostingsWriter, which eventually calls the size()
> method in ByteBuffersDataOutput.}}
> {code:java|title=ByteBuffersDataOutput.java|borderStyle=solid}
> public long size() {
> long size = 0;
> int blockCount = blocks.size();
> if (blockCount >= 1) {
> int fullBlockSize = (blockCount - 1) * blockSize(); // throws integer
> overflow
> int lastBlockSize = blocks.getLast().position();
> size = fullBlockSize + lastBlockSize;
> }
> return size;
> }
> {code}
> In my case, I had a blockCount = 65 and a blockSize() = 33554432 which
> overflows fullBlockSize. The fix:
> {code:java|title=ByteBuffersDataOutput.java|borderStyle=solid}
> public long size() {
> long size = 0;
> int blockCount = blocks.size();
> if (blockCount >= 1) {
> long fullBlockSize = 1L * (blockCount - 1) * blockSize();
> int lastBlockSize = blocks.getLast().position();
> size = fullBlockSize + lastBlockSize;
> }
> return size;
> }
> {code}
>
> Thanks
