> MMAP mode has a bunch of problems (see for example http://www.mapdb.org/blog/mmap_files_alloc_and_jvm_crash/ )
> Users are increasingly stumbling over these issues especially in virtualized environments.
> MMAP should be disabled by default because it requires additional care from user stand point.
