[jboss-jira] [JBoss JIRA] Closed: (JASSIST-33) Javassist gets confused when creating method wrappers for fields that exist in the package name

Javassist gets confused when creating method wrappers for fields that exist in the package name ----------------------------------------------------------------------------------------------- Key: JASSIST-33 URL: http://jira.jboss.com/jira/browse/JASSIST-33 Project: Javassist Issue Type: Bug Reporter: Kabir Khan Assigned To: Shigeru Chiba Hi Chiba, There is a problem with weaving a class: package org.jboss.test.aop.regression.jbaop398nosuchfield; public class POJO { private static String org = "Fail"; public int method() { return 0; } //Want to weave in this method public String org_r_aop() { return org.jboss.test.aop.regression.jbaop398nosuchfield.POJO.org; } } We get this stack trace: javassist.CannotCompileException: [source error] no such field: jboss at

javassist.CtBehavior.setBody(CtBehavior.java:358) ... 45 more [error] failed to transform: org.jboss.test.aop.regression.jbaop398nosuchfield.POJO.. Do verbose mode if you want full stack trace. I think it might have to do with the field having the same name as one of the package name elements, but am not sure! Cheers, Kabir
