--------------------------------------------
Summary: 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
byteCount overflows and causes an IllegalArgument exception in Memory.allocate
when bloomfilter is > 2GB.
Suggest changing byteCount to long.
{code}
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}
