Use of unexported JVM class in Bitbucket plugin

[Paul Stein]

In the Bitbucket plugin project I am working on I am using  kerb4j-client  in order to establish kerberized connection to 3rd party service.

<dependency>
    <groupId>com.kerb4j</groupId>
    <artifactId>kerb4j-client</artifactId>
    <version>0.0.8</version>
    <scope>compile</scope>
</dependency>

kerb4j-client  depends on  kerb4j-common  which in turn refers to  com.sun.security.auth.module.Krb5LoginModule  class which is the one I am getting NoClassDefFoundError when trying to run the plugin flow.

The  Krb5LoginModule  is a part of JVM and exists in both JDK/JRE's rt.jar,  at least as of the v1.8.0_181 I am using.

I checked the  MANIFEST.MF  from the plugin jar and do see  "com.sun.security.auth.module;version=0;resolution:=optional"  there

I checked  /plugins/servlet/upm/osgi  on the server but when expanding my plugin "Import Package" section the report around it looks like this:

com.google.gson    version: 0, resolution: optional
Provided by System Bundle

com.sun.security.auth.module    version: 0, resolution: optional

javax.annotation    version: 0, resolution: optional
Provided by System Bundle

Understandably, when looking under System Bundle "Export Package" no  com.sun.security.auth.module  is listed.

What would be the approach to resolve this?

Approach, is using the last version of spring scanner
