-XX:+PrintAOT Output: First Two Columns Are...?

[Gary Morrison]

Apologies in advance if this is too elementary a question.  First time posting here.  (Also, admittedly not strictly a Graal question, but obviously related.)

Googled around a bit but couldn't really find anything.

With -XX:+PrintAOT, what are the first two columns of info.  They're numerical, so I'm guessing they're some sort of time-stamp?  Referring to the 43-44 and the 1-10 below, for example:

     43    1     aot[ 2]   java.lang.Object.finalize()V
     43    2     aot[ 2]   java.lang.Object.equals(Ljava/lang/Object;)Z
     43    3     aot[ 2]   java.lang.Object.<init>()V
     43    4     aot[ 2]   java.lang.Object.wait()V
     43    5     aot[ 2]   java.lang.Object.<clinit>()V
     43    6     aot[ 2]   java.lang.Object.wait(JI)V
     43    7     aot[ 2]   java.lang.Object.toString()Ljava/lang/String;
     43    8     aot[ 2]   java.lang.CharSequence.chars()Ljava/util/stream/IntStream;
     44    9     aot[ 2]   java.lang.CharSequence.codePoints()Ljava/util/stream/IntStream;
     44   10     aot[ 2]   java.lang.CharSequence.lambda$codePoints$1()Ljava/util/Spliterator$OfInt;
