Primitive test case

Attaching a simple test case.

Win7: Maximal size is: 0x71000000 (1.765625 GB)
Wine: Maximal size is: 0x41000000 (1.015625 GB)

I checked the memory mappings as well:
Windows: 0x01000000 - 0x72000000 is available
Wine:    0x20000000 - 0x62000000 is available

Not sure why the massive difference though.

Stupid hack to work around the issue

Attaching a stupid hack that makes java start. What exactly is this "low memory
area" in the first place?

I found similar issues:
- bug 26085 (although I don't agree the WONTFIX)
- bug 48172 (about heap allocation in general)

Should we merge the bugs somehow?
