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

[Vladimir Kozlov]

Hi Gary,

I assume you are asking about AOT feature in JDK.

$ java -XX:+PrintAOT -XX:AOTLibrary=./aot.so HelloWorld
      87    1     loaded    ./aot.so  aot library
     277    1     aot[ 1]   HelloWorld.<init>()V
     277    2     aot[ 1]   HelloWorld.main([Ljava/lang/String;)V

First column is milisec from JVM start.
Second - ID assigned to AOTed method.
Third in [] is AOT library Id (in order they are loaded)

Regards,
Vladimir
