             Summary: Bufferpool integer size overflow w/ entries >2GB
                 Key: SYSTEMML-1032
             Project: SystemML
          Issue Type: Bug
    Affects Versions: SystemML 0.11
            Reporter: Matthias Boehm
            Assignee: Matthias Boehm
            Priority: Blocker

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.
