A DESCRIPTION OF THE PROBLEM :
The class documentation of SecureRandom contains examples which have [] on the variable instead of on the type. While valid, this is very uncommon & should be changed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
byte[] bytes = new byte[20];

byte[] seed = random.generateSeed(20);
ACTUAL -
byte bytes[] = new byte[20];

byte seed[] = random.generateSeed(20);
