NottyCode commented 4 years ago

Describe the bug The Open Liberty website has the following REST client class: https://github.com/OpenLiberty/openliberty.io/blob/master/src/main/java/io/openliberty/website/dheclient/BuildStore.java

It is failing in production with this error:

Strange that it is intermittent... I've seen something similar to this with the IBM JDK 8. This is dealing with the invocation of default interface methods on the dynamic proxy instance. In Java SE 9, there is a new MethodHandles.Lookup method called privateLookupIn that can access default interface methods. In Java SE 8, it is not possible to invoke default interface methods on a proxy object reflectively without using internal JDK methods. My guess is that the IBM JDK changed their internal JDK method somewhat which is throwing this code off.
