Reporting duplicated classes in JBoss EAP

Sometimes an artifact itself do not have duplicated classes, but once deployed its environment can provide classes already present on it.

I'm thinking on check a BOM like https://mvnrepository.com/artifact/org.jboss.bom/jboss-eap-javaee7/7.1.5.GA

against an artifact and detect such duplicities

Something like:

java -Xmx512m -jar tattletale-eap6.jar yourapplication.war -bom "org.jboss.bom/jboss-eap-javaee7/7.1.5.GA" report

This can be fixed by building Tattletale with <property name="version.javassist" value="3.19.0-GA"/> in the build.xml.

Bug: ant:tattlereport throwing ClassCastException

Expected
That TattleReport run without producing errors, or if an error does occur that it explains what the error is. No unhandled exceptions are expected -- TattleReport is expected to gracefully handle malformed input and similar.

Actual
The following stack trace is shown in our build system:

[ant:tattletaleReport] java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long

Repro

• It's reproducible every time in my build environment, but I have not yet isolated what is different about my build system. See the notes below though.

Notes
Looking at the code we see the following: https://github.com/jesperpedersen/tattletale/blob/master/src/main/java/org/jboss/tattletale/analyzers/AbstractScanner.java#L190

  Long serialVersionUID = null;
  try
  {
     CtField field = ctClz.getField("serialVersionUID");
     serialVersionUID = (Long) field.getConstantValue();
  }
  catch (NotFoundException nfe)
  {
     // Ignore - not serializable
  }

Therefore it seems likely that the serialVersionUID's value is an Integer, and hence why it's having trouble casting this to a Long.

maven freindly

to convert to Maven (pom based) project model, who's blessing is needed ?

XML report

Is it possible to have an XML report?
