----------------------------------------
Summary: Rework SerializedThrowableTest to not use Unsafe.defineClass()
Key: FLINK-13460
URL:
https://issues.apache.org/jira/browse/FLINK-13460 Project: Flink
Issue Type: Sub-task
Components: Tests
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.10.0
The method {{Unsafe.defineClass()}} is removed in Java 11.
To support Java 11, we need to rework the method {{CommonTestUtils.createClassNotInClassPath()}} to use a different mechanism.
Java 11 introduces a new way to define a class from byte code via {{MethodHandles}}. However, because these do not exist in Java 8, we cannot use them if we want to keep supporting Java 8, which we most likely want to do for quite a while.
