32 bit JVM memory heap issue on 64 bit XP

My application runs perfectly alright on 32 bit XP and JVM could allocate 1.4 GB object heap size to this application. But when I run the same application (with 32 bit JVM), it could not initialize JVM. Then I tried reducing max heap size and at 1056MB, it started working!

XP 64-bit machine has 11GB RAM and 2GB virtual memory.

Does anyone any idea as what is the solution to this problem?

Why are you using the 32-bit JVM on 64-bit Windows?
Try using the 64-bit JVM.

I can not use 64 bit JVM and the product is already out in the market and I am shipping 32 bit JRE alongwith installer itself.
