             Summary: Coverity: dereference null value in ClassLoadingAttributeDefinitions (Elytron subsystem)
                 Key: ELY-845
                 URL: https://issues.jboss.org/browse/ELY-845
             Project: WildFly Elytron
          Issue Type: Bug
            Reporter: Josef Cacek
            Assignee: Darran Lofthouse


Coverity static-analysis scan found a possilbe method call on null object in the {{ClassLoadingAttributeDefinitions.resolveClassLoader}} method.

https://scan7.coverity.com/reports.htm#v16159/p12663/fileInstanceId=6892131&defectInstanceId=1794525&mergedDefectId=1388482
Following code
{code:java}
Module current = Module.getCallerModule();
if (module != null) {
    ModuleIdentifier mi = ModuleIdentifier.fromString(module);
    current = current.getModule(mi);
{code}

The {{current}} value returned from {{Module.getCallerModule()}} may be {{null}}. The {{getModule()}} method is called on it without the null-check.
