15:33:05  ---SUMMARY OF FAILED TESTS---
15:33:05  Test 57-a: Make sure that lambda classes work and get stored in the shared class cache
15:33:05  Test 57-b: Make sure that lambda classes are stored in the cache as orphans
15:33:05  Test 57-c: Make sure that when the program runs again lambda classes are used from the cache and not stored again
15:33:05  Test 58: Make sure that when the program runs again without the first lambda class, the second lambda class is still used from the cache and not stored again
15:33:05  Test 59-a: Run and store 10 lambda classes in the cache
15:33:05  Test 59-b: Do not run the first lambda class to check if a class with 1 digit index number gets matched to the one stored in the cache but with 2 digits index number (10th class in the previous run will be matched to 9th in this run)
15:33:05  Test 60-a: Make sure that lambda classes work and get stored in the cache when another function with lambda classes in another file is being called from the current file
15:33:05  Test 60-b: Make sure that the classes are used from the cache when the program is being run again

Discussed with @hangshao0 this is a test problem.

It was

The openjdk change was https://github.com/ibmruntimes/openj9-openjdk-jdk/commit/89cb6a4857eb80f3de4969341dc55accccfe1925

8292914: Lambda proxies have unstable names Change the name of generated lambda proxy classes so that they no longer have a numerical suffix.
