RoboShadowDid you install java?

You MUST have Java to use Minecraft, you can't play MC at all w/o Java, the only thing that would say is an error message

PS: To @OP about the crash, since it said "NullPointerException", a NullPointerException

According to something online, a nullpointerexception is:

Thrown when an application attempts to use null in a case where an object is required. These include:
Calling the instance method of a null object.
Accessing or modifying the field of a null object.
Taking the length of null as if it were an array.
Accessing or modifying the slots of null as if it were an array.
Throwing null as if it were a Throwable value.

Applications should throw instances of this class to indicate other illegal uses of the null object. NullPointerException objects may be constructed by the virtual machine as if suppression were disabled and/or the stack trace was not writable.

I assume it was caused by a bug that called the instance method of a null (in my opinion, it should [or must] mean non-existant) object.

EDIT: In my opinion it is a bug/glitch in either Minecraft and/or Java
