This is case 65341881.

This seems to be a regression in 1.4.2 recent releases.
This problem happens only on windows 2000, not even on windows xp.

C:\j2sdk1.4.2_13\bin>java -Xmx1400m -version
Error occurred during initialization of VM

Yumin has a preliminary evaluation on this issue:

"I tested the binary based on this putback and the binary before this 
putback --- the result showed after CR 4515367, this problem occured. If 
customer filed escalation I could work again on the case to find more 
detail information. Now the only finding is the putback caused this 
change. 5.0 is not haveing this problem."

EVALUATION In bug fix of 4515367 (Exception error handling clean up), in VM_Version_init() stack, there is a call to strdup which duplicates a string in heap, somehow this action led to memory fragmented precedes universe_init() which has the biggest memory chunk allocation request. If change the initialization sequence make universe_init() precedes VM_Version_init(), see "Suggested Fix", the problem would go away.
