 Regarding your issue, According to the error log in [1] it seems like a
 CNF problem. Log says the it cannot find "java.lang.Class$Atomic" class.
 CNF exception is thrown from the static block in
 org.wso2.msf4j.util.RuntimeAnnotations class [3] where
 "java.lang.Class$Atomic" class is loaded using Class.forName() method.

 @ThusithaD, is there a workaround or a solution for this?

Re: [Dev] Issue when running UUFMicroservice on top of IBM JDK 8

[Thusitha Thilina Dayaratne]

Hi Sajith,

I agree that using JDK private/internal classes might cause undesired
issues in the future. We might need to figure out some other way to cater
the UUF requirement in order to change the Service path at Runtime.
I've created the issue[1] to track this.

Thanks
Thusitha

 Hi,

 When starting the IS 6.0.0 pack on top of IBM JDK 8 latest version we
 get the error reported at [1].
 The other microservices in the pack are added without an issue. I also
 tested a micro service sample and it works fine on ibm jdk.
 But when come to org.wso2.carbon.uuf.httpconnector.msf4j.UUFMicroservice
 it throws the reported error.
 After that cannot visit the User portal app as well.

 Are we supporting IBM jsk 8 for uuf? Any insight on this will be
 helpful.

You are loading following classes using Class.forName() method,

sun.reflect.annotation.AnnotationInvocationHandler [1] - this is an
internal class of the JDK and we shouldn't be using this as it might
changed in a future JDK version.
java.lang.Class$Atomic [2] - this is a private inter class of the
java.lang.Class class
java.lang.Class$AnnotationData [3] - again this is a private inner class of
the java.lang.Class class


Using private/internal classes (that are not part of the public API) of the
JDK is extremely unstable as they might changed in future releases (even in
minor version releases). So, we need to figure out a way to avoid above
mentioned classes.

Re: [Dev] Issue when running UUFMicroservice on top of IBM JDK 8

[Thusitha Thilina Dayaratne]

It seems that IBM JDK doesn't contain the particular class whereas Oracle
and OpenJDK contain the class. According to[1] we are recommending Oracle
and Open JDK only. Therefore we may have to decide whether we should
support IBM JDK as well.

Re: [Dev] Issue when running UUFMicroservice on top of IBM JDK 8

[SajithAR Ariyarathna]

According to [2] (see "Oracle content" section) IBM JDK 8 has Nashorn in
it. So, UUF should work in IBM JDK :).

Regarding your issue, According to the error log in [1] it seems like a CNF
problem. Log says the it cannot find "java.lang.Class$Atomic" class. CNF
exception is thrown from the static block in
org.wso2.msf4j.util.RuntimeAnnotations class [3] where
"java.lang.Class$Atomic" class is loaded using Class.forName() method.

@ThusithaD, is there a workaround or a solution for this?
