Re: Error --GC Cleaner Provider -- Flink 1.11.0

Hi Murali, A proper fix of this problem could take some time. It may or may not catch the next bug-fix release (1.11.1). At the meantime, you can try to workaround this by upgrading your JDK8 to a recent release. E.g., the latest JDK8u252 [1]. Thank you~ Xintong Song [1] https://adoptopenjdk.

I think the problem is that the package-private method `Reference.tryHandlePending` does not exist in 1.8.0_40. The method does not exist in OpenJDK 8u40[1], but can be found in the latest AdoptOpenJDK [2]. It seems the method was first introduced in 8u202[3]. Thank you~ Xintong Song [1] https:
