> Integer overflow in OffHeapBitSet when bloomfilter > 2GB
> --------------------------------------------------------
>
> Key: CASSANDRA-5903
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5903
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Taylan Develioglu
> Fix For: 1.2.9
>
>
> In org.apache.cassandra.utils.obs.OffHeapBitSet.
> byteCount overflows and causes an IllegalArgument exception in Memory.allocate when bloomfilter is > 2GB.
> Suggest changing byteCount to long.
> {code:title=OffHeapBitSet.java}
> public OffHeapBitSet(long numBits)
> {
> // OpenBitSet.bits2words calculation is there for backward compatibility.
> int byteCount = OpenBitSet.bits2words(numBits) * 8;
> bytes = RefCountedMemory.allocate(byteCount);
> // flush/clear the existing memory.
> clear();
> }
> {code}
