G1, Paralle and Serial all log incorrect page sizes with os::trace_pages().
For G1 the parameter order is wrong and in Parallel and Serial the large_page_size will always be used even if the mappings fail.
I've created a test that catch those issues but there are also problems when tracing the code heaps (seeJDK-8261029), so the test can't be added until a fix for that is integrated as well.
The test is available here for now:
