Maven Verify failing on java6
Hi Guys,
I just noticed that "mvn verify" is failing on master:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile
(default-testCompile) on project flink-runtime: Compilation failure
[ERROR]
/home/travis/build/aljoscha/incubator-flink/flink-runtime/src/test/java/org/apache/flink/runtime/io/network/netty/OutboundConnectionQueueTest.java:[157,70]
type parameters of <T>T cannot be determined; no unique maximal instance
exists for type variable T with upper bounds boolean,java.lang.Object
We had this problem before, does anyone remember what the problem is with
java6 here? Also, I'm not filing a bug but posting this here since it
should be handled quickly because a failing build looks bad.

Travis told me it's alright now. :D

I've changed this.
Could you checkout the current master and then report back? :)

Or try "boolean hasRequestedClose = Whitebox.<Boolean>getInternalState(queue,
"hasRequestedClose");"

I think the problem is with the way I use PowerMock in the test:
boolean hasRequestedClose = Whitebox.getInternalState(queue, "hasRequestedClose");
Could you try whether changing it to Boolean works?
Best,
Ufuk

Hi,
are you using OpenJDK or OracleJDK? There is a unfixed bug in Oracle JDK 6,
but I think that leads to a null pointer exception in the compiler.
Travis was able to build the current master with OpenJDK6 yesterday:
