Minor Description
I observed that some of the test cases using PowerMockRunner fail with Java 8u20 with the following error:
java.lang.VerifyError: Bad <init> method call from inside of a branch
Exception Details:
Location:
org/apache/flink/client/program/ClientTest$SuccessReturningActor.<init>()V @32: invokespecial
Reason:
Error exists in the bytecode

Affected tests are: ClientTest.shouldSubmitToJobClient, ClientTest.shouldSubmitToJobClientFails, DataSourceTaskTest, DataSinkTaskTest and ChainTaskTest. This list, however, is by no means complete.
With the latest java version Java 8u51, the tests pass, though. The problem might be related to https://code.google.com/p/powermock/issues/detail?id=505 and to https://bugs.openjdk.java.net/browse/JDK-8051012
I propose to either document this fact more prominently or to rewrite the affected tests so that they also run with Java 8u20.
