You should change it to `%4d`. Otherwise, when the numbers are changed in the future (e.g., to 3 or 4 digits) they will be misaligned: KlassAddr Size State Flags ClassName 0x0000000800df8400 62 fully_initialized W java.lang.invoke.LambdaForm$DMH/0x0000000800df8400 0x0000000800df8000 123 fully_initialized W java.lang.invoke.LambdaForm$DMH/0x0000000800df8000 0x0000000800de4400 4567 fully_initialized W java.lang.invoke.LambdaForm$DMH/0x0000000800de4400 ------------- PR: https://git.openjdk.java.net/jdk/pull/7105
