A question concerning

[The Metal Maniac]

So yeah, I've got a bunch of icons on my desktop, and they're all titled what I've got in the sub-title, only with different numbers.

 

They're all notepad files, and when I open them, I get:

 

#

# An unexpected error has been detected by HotSpot Virtual Machine:

#

#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x77f5b386, pid=358348, tid=358304

#

# Java VM: Java HotSpot Client VM (1.5.0-beta-b32c mixed mode)

# Problematic frame:

# C  [ntdll.dll+0xb386]

#

 

And so on. They're pretty big, and have a lot of Java-looking stuff in them. So...what are they? What are they for? Can I safely delete them form my PC? I have no idea where they came from or why they're there. Any help?
