I started to map special(-n) to nosafepoint(-n) but since special is nosafepoint - 9 (?) there were interactions with other nosafepoint locks so they needed rankings relative to other locks. CompiledMethod_lock(nosafepoint-4) -> CodeCache_lock(nosafepoint-3) -> VtableStubs_lock(nosafepoint-2) -> CompiledIC_lock(nosafepoint) CodeSweeper_lock(nosafepoint-5) -> CompiledMethod_lock(nosafepoint-4) ThreadsSMRDelete_lock(nosafepoint-2) -> (can't remember which one was nosafepoint-1 anymore!) The compiler locks have the deepest nestings. ------------- PR: https://git.openjdk.java.net/jdk/pull/5563
