The 32-bit Client VM was removed from linux-x86 and Windows. As a result, the `-client` flag is ignored with 32-bit versions of Java on this platform. The 32-bit Server VM is used instead. However, due to limited virtual address space on Windows in 32-bit mode, by default the Server VM emulates the behavior of the Client VM and only uses the C1 JIT compiler, Serial GC, 32Mb CodeCache. To revert to server mode, the flag `-XX:{+|-}TieredCompilation` can be used. On linux-x86 there is no Client VM mode emulation.
