The number of cached adapters and performance improvement are still here:

$ (perf stat -r 100 ./build/product/images/jdk/bin/java -XX:AOTCache=app.aotcache -XX:+UnlockDiagnosticVMOptions -XX:+AOTAdapterCaching -cp hello.jar HelloWorld > /dev/null) 2>&1 | grep elapsed
         0.0247033 +- 0.0000319 seconds time elapsed  ( +-  0.13% )

vs w/o AOT adapters:
         0.0266180 +- 0.0000352 seconds time elapsed  ( +-  0.13% )
