@eme64 How do I use the TraceMergeStores option? It worked before, but now it gives an error.


build/macosx-aarch64-server-fastdebug/jdk/bin/java -Dtest=appendNullLatin1 -XX:+TraceMergeStores


output

Unrecognized VM option 'TraceMergeStores'
Did you mean '(+/-)MergeStores'?
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
