Java 8 JDK Issue

Matthias J. Sax-2
Hi,

I just hit a issue with Java 8 JDK. It occurs in a new test I added in a
current PR.

I have not clue what the problem might be. Searching on the Internet did
not help...

Does anyone have an idea what the problem might be?

Re: Java 8 JDK Issue

Stephan Ewen
Do you know between what classes the exception is? What is the original
class and what the cast target class?

Are they both the same, and not castable because of different copies being
loaded from different classloaders, or are they really different types?

Re: Java 8 JDK Issue

Matthias J. Sax-2
Not right now... The ClassCastException occurs deeply inside Storm. I
guess it is a Storm issue.

I just instantiate a (Storm)LocalCluster and it fails internally.

> LocalCluster cluster = new LocalCluster();

Maybe I need to try it locally with Java 8 JDK to be able to debug it...
I will pick up this thread again if I have more information.

As a fall back, we might want to deactivate this test for Java 8 (if
this is possible).

Re: Java 8 JDK Issue

Matthias J. Sax-2
Hi,

using Java 8 locally, I was able to reproduce the problem. I dug into it
and could figure out the following. However, I cannot make any sense out
of it. I have no experience with Java security stuff...

Anyone?

-Matthias

========================================================================

In class
> javax.security.auth.login.Configuration.getConfiguration()

in line 235 to 242 (for Java 7) and
in line 232 to 239 (for Java 8)
       
this code

> String config_class = null;
> config_class = AccessController.doPrivileged
>     (new PrivilegedAction<Stritype filter textng>() {
>     public String run() {
>         return java.security.Security.getProperty
>                     ("login.configuration.provider");
>     }
> });

results for "config_class":
  Java 7: com.sun.security.auth.login.ConfigFile
  Java 8: sun.security.provider.ConfigFile

Later this leads to ClassCastException (in line 254 to 257 for Java 7;
and line 251 to 254 for Java 8)

> Class<? extends Configuration> implClass = Class.forName(
>         finalClass, false,
>         Thread.currentThread().getContextClassLoader()
> ).asSubclass(Configuration.class);

The call stack is also somewhat different.

Java 7:

> Configuration.getConfiguration() line: 235
> NIOServerCnxnFactory(ServerCnxnFactory).configureSaslLogin() line: 174
> NIOServerCnxnFactory.configure(InetSocketAddress, int) line: 87

> LocalCluster.clj line: 28
> LocalCluster.<init>() line: not available
> StormWrapperSetupHelperTest.testCreateTopologyContext() line: 190
Java 8:

> Configuration$2.run() line: 254 [local variables unavailable]
> Configuration$2.run() line: 247
> AccessController.doPrivileged(PrivilegedExceptionAction<T>) line: not available [native method]

Re: Java 8 JDK Issue

Stephan Ewen
No clue, sorry.

The Storm Mailing list may be able to help you, it looks like deep into
their code...

Re: Java 8 JDK Issue

Matthias J. Sax-2
Hi,

fixed it... After trying (without success) to build a minimum Java 8
example that fails (a new project extern to Flink), it was clear that
JDK 8 is actually not the problem.

I did some more debugging an figured out, that different class loader
are used here (for the external new Java 8 and original Flink Java 8 test)

> Class<? extends Configuration> implClass = Class.forName(
>         finalClass, false,
>         Thread.currentThread().getContextClassLoader()
> ).asSubclass(Configuration.class);

In the Flink Java 8 case, it was a "MockClassLoader". This reminded me,
that I had a previous Java 7 issue, that I resolved my added a test
annotation.

> @PowerMockIgnore("javax.managment.*")

Now I changed this to

> @PowerMockIgnore("javax.*")

which fixed it. The problem was, that the annotation disabled
MockClassLoader for a too limited "package space" in Java 8.
