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.
