Problem is, that default build of 32-bit windows JDK does not include Client VM, so Server VM is used (so -client arg does nothing). With Server VM tests fails. I tried to make build which has Client VM and then this test passes (It breaks other tests which expect default to be Server VM though).

Even though, I should test that VM launched with "-client" uses Client VM (maybe case where it has Client VM but it is not default). I would then probably need to run test in othervm and with -client arg as well.
