EVALUATION This was failing with 64k (or larger) base page sizes due to having defaults that weren't aligned (codeCache) or our policy of subtracting 3 guard pages (ThreadStackSize). We need to round the code cache to the os's page size. The approriate (least amount of surprise) fix for the ThreadStackSize problem is to leave it as is for 8k page sizes (subtracting the 3 pages) but for larger than 8k pages, we'll ADD the 3 guard pages to the size requested.

WORK AROUND Workaround would be: -XX:InitialCodeCacheSize=196608 -Xss512k

SUGGESTED FIX There are 2 problems to fix. One in src/os/solaris/vm/os_solaris.cpp, after discussions with Dave Dice and Dave Stoutamire on the ThreadStackSize problem produced this code in os::init_2() // For Solaris 10+, there will be a 64kb page size, which makes // the usable default stack size quite a bit less. Increase the // stack for 64kb (or any > than 8kb) pages, this increases // virtual memory fragmentation (since we're not creating the // stack on a power of 2 boundary. The real fix for this // should be to fix the guard page mechanism. if (vm_page_size() > 8*K) { threadStackSizeInBytes = (threadStackSizeInBytes != 0) ? threadStackSizeInBytes + (3 * vm_page_size()) : 0; ThreadStackSize = threadStackSizeInBytes/K; } Then in src/share/vm/code/codeCache.cpp I changed the "checks" for alignment to "round_up" // This was originally just a check of the alignment, causing failure, instead, round // the code cache to the page size. In particular, Solaris is moving to a larger // default page size. CodeCacheExpansionSize = round_to(CodeCacheExpansionSize, os::vm_page_size()); InitialCodeCacheSize = round_to(InitialCodeCacheSize, os::vm_page_size()); ReservedCodeCacheSize = round_to(ReservedCodeCacheSize, os::vm_page_size());
