I chose the assert because if it is safe > to access `Method` than its holder `Klass` must be alive. Hi, the code is safe. Not because of the checks cited by @eastig but because print_names() is only called if the required locks (Compile_lock and CodeCache_lock) have been continuously held since the aggregation step. See src/hotspot/share/compiler/compileBroker.cpp. A lot of effort has been spent to be less restrictive on print_names(), with no success. Thanks for the enhancement. - PR: https://git.openjdk.java.net/jdk/pull/6200
