        Description

        heapDumper doesn't check the size of segment while dumping an array. So if (bytes written to segment + length of array) > max_juint it overflows u4 segment length field and crash later on assert in heapDumper.cpp:

        assert(dump_len >= 0 && dump_len <= max_juint) failed: bad dump length
