A bug in the LongConverter.java file causes variables of type Long to be serialized and thereby be transmitted incorrectly.

The error is in this code snipped:

[...] (MASK << (i * BYTE_LENGTH)) [...]

Because MASK is of type int, the shift can cause unwanted results.

A quick fix could be to change MASK to type long, but the proposed solution in the patch file additionally reduces the number of operations and shortens the line of code.
