A DESCRIPTION OF THE PROBLEM :
The documentation for Long.parseLong(String s, int radix) indicates that the letter 'L' or 'l' may not be in the string, " except that either L or l may appear as a digit for a radix greater than 22. " L and l can also appear if the radix is equal to 22; this should be " greater than or equal " . The same error is in the documentation of Long.valueOf(String s, int radix).

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
 " except that either L or l may appear as a digit for a radix greater than or equal to 22. "
ACTUAL -
 " except that either L or l may appear as a digit for a radix greater than 22. "
