I think we should just fix it for CodeCacheExpansionSize

-          range(os::vm_page_size(), max_uintx)                              \
+          range(32*K, max_uintx)                                            \

The default values for the other flags are much larger than vm_page_size() and definitely should be.

I can take care of fixing this - since I also broke it :)

Thanks for reporting!

Best regards,
Tobias
