-----------------------------------

             Summary: Incompatible type error with @Cause and ctors with unusual exception types
                 Key: LOGTOOL-134
                 URL: https://issues.jboss.org/browse/LOGTOOL-134
             Project: Log Tool
          Issue Type: Bug
    Affects Versions: 2.1.0.Final
            Reporter: David Lloyd
            Priority: Minor


Incorrect generated code can be generated if an exception constructor's "cause" parameter is a subtype of {{Throwable}} (say, {{Exception}}) instead of being {{Throwable}} itself, and a {{\@Cause}} parameter exists whose type is a superclass of that type (say, {{Throwable}}).

The compilation errors can look something like this:
{noformat}
2018-04-02 12:37:40 [ERROR] /home/david/src/java/wildfly/ejb3/target/generated-sources/annotations/org/jboss/as/ejb3/logging/EjbLogger_$logger.java:[3340,112] incompatible types: java.lang.Throwable cannot be converted to java.lang.Exception
2018-04-02 12:37:40 [ERROR] /home/david/src/java/wildfly/ejb3/target/generated-sources/annotations/org/jboss/as/ejb3/logging/EjbLogger_$logger.java:[3479,164] incompatible types: java.lang.Error cannot be converted to java.lang.Exception
{noformat}

If the {{\@Cause}} method parameter type is not assignable to the exception's cause parameter type, then the {{initCause}} strategy should be used instead.
