Hello everyone!
When File.createTempFile() is called, a random long value is generated,
which is then made positive with Math.abs() and then used as a part of
the directory name.
Instead of using Math.abs() and Long.toString(), it would be better to
use Long.toUnsignedString():
1) no need to deal with the corner case of Long.MIN_VALUE,
2) increase the space of random values by the factor of 2.
Would you please help review the fix?
