Null Pointer Exception

Null Pointer Exception,
you're in a class of your own.
I will try and catch you,
each instance you're thrown.

Null objects expel you,
because you are vile.
I dread that I'll c you,
when I attempt to compile.

Like the grim reaper,
you destroy lines of code.
And so to you,
I dedicate this ode.

You have no remorse
for those who won't test.
As a result,
I need to confess.

From time to time,
when there's no time waste.
I must rely
on cut and on paste.

Although we're acquainted,
I really must mention.
You're not my friend,
Null Pointer Exception.
