No such field: jboss
--------------------

                 Key: JBAOP-398
                 URL: http://jira.jboss.com/jira/browse/JBAOP-398
             Project: JBoss AOP
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.0.0.alpha4, 1.5.5.GA
            Reporter: Flavia Rainone
             Fix For: 2.1.0.GA, 1.5.6.GA

If a POJO class being instrumented has a field called "org", jboss aop will eventually throw an exception with this error message (it might be after setting a field wrapper body, or after CtCasslass.toByteCode() , for example).

An example is:

javassist.CannotCompileException: [source error] no such field: jboss
        at javassist.CtBehavior.setBody(CtBehavior.java:364)
        at javassist.CtBehavior.setBody(CtBehavior.java:333)
        at org.jboss.aop.instrument.OptimizedFieldAccessTransformer.buildWrappers(OptimizedFieldAccessTransformer.java:278)
        at org.jboss.aop.instrument.OptimizedFieldAccessTransformer.doBuildFieldWrappers(OptimizedFieldAccessTransformer.java:100)
        at org.jboss.aop.instrument.FieldAccessTransformer.buildFieldWrappers(FieldAccessTransformer.java:102)
        at org.jboss.aop.instrument.Instrumentor.transform(Instrumentor.java:724)
        at org.jboss.aop.ClassicWeavingStrategy.translate(ClassicWeavingStrategy.java:107)
        at org.jboss.aop.AspectManager.translate(AspectManager.java:910)
        at org.jboss.aop.AspectManager.transform(AspectManager.java:853)
        at org.jboss.aop.standalone.AOPTransformer.aspectTransform(AOPTransformer.java:88)
        at org.jboss.aop.standalone.AOPTransformer.transform(AOPTransformer.java:75)

The moment in which the exception is being thrown seems to have to do with what joinpoint of POJO class are being instrumented. If the "org" field is being intercepted, the moment in which the field wrapper body is being set is the moment in which javassist throws the exception. If the field "org" is not being intercepted, it seems that the moment in which the exception is being thrown is right after jboss aop instrumentation execution, when toByteCode method is invoked.
