Description

The recent buffer pool integration of frames in SYSTEMML-968 introduced a buffer pool integer overflow. This only shows up with heap sizes >13.5GB, entries >2GB, and shallow serialize (dense or CSR). Potential errors are OOMs or NoSuchElementException from the buffer pool on eviction as the buffer pool cannot be cleaned to size 0 anymore.
