java.lang.ClassFormatError: class com.jsoniter.IterImpl cannot access its superclass com.jsoniter.IterImplForStreaming

[mferretti]

Hi,
I am facing an odd issue running tests for my app with arquillian: whenever I try to parse a json (stream) with JSonIterator the test fails with the following exception :
`
...
Caused by: javassist.CannotCompileException: by java.lang.ClassFormatError: class com.jsoniter.IterImpl cannot access its superclass com.jsoniter.IterImplForStreaming

`

Looking at the code (DynamicCodegen) I see
public static void enableStreamingSupport() throws Exception { CtClass ctClass = pool.makeClass("com.jsoniter.IterImpl"); ctClass.setSuperclass(pool.get(IterImplForStreaming.class.getName())); ctClass.toClass(); }

Following the stack trace it seems that the exception is thrown in
`
public Class toClass(CtClass ct, Class<?> neighbor, ClassLoader loader,
ProtectionDomain domain)

`

Where

`
ct =IterImplForStreaming

neighbor=null

loader = org.jboss.shrinkwrap.api.classloader.ShrinkWrapClassLoader

domain = null

`

Could you please shed some light into this ?

jsonIter : 0.9.23
javaassist : 3.24.1-GA
shrinkwrap: 1.2.6
arquillian: 1.4.1

Cheers

@mferretti Have you found a solution for your problem in the meantime?

nope. Since there was no coming back on this, and due to the fact that arquillian was a mandatory requirement for the project, we simply moved to jackson.

Since the project looks dead I don't expect anything coming from this. I might fork this repo (provided I can schedule some time to look into it). For the time being I am closing this issue
