[jboss-jira] [JBoss JIRA] Commented: (JASSIST-136) getDeclaringClass() throws IncompatibleClassChangeError on copy of inner class
[
https://issues.jboss.org/browse/JASSIST-136?page=com.atlassian.jira.plugi...

Shigeru Chiba commented on JASSIST-136:
---------------------------------------
If a class A is a static nested class in class B, then both A and B have a special
attribute indicating that A is in B. So when you make a copy of A and name it A2, B's
attribute must be updated to indicate A2 is also in B. Unfortunately, Javassist does not
support such an update. I will check supporting it is possible.
Furthermore, according to Java's naming convention, GetDeclaringClassTest$Foo$BackRef
is a static nested class BackRef in Foo, which is a nested class in GetDeclaringClassTest.
In this case, updating attributes is more complex.
getDeclaringClass() throws IncompatibleClassChangeError on copy of

Key: JASSIST-136
URL: https://issues.jboss.org/browse/JASSIST-136
Project: Javassist
Issue Type: Bug
Affects Versions: 3.14.0.GA
Environment: sun jdk1.6.0_21
Reporter: Ragnar Rova
Assignee: Shigeru Chiba
Creating a copy of a inner class and then calling getDeclaringClass() on the copied class
causes error. How to create a copy of such a class?
java.lang.IncompatibleClassChangeError: foo.GetDeclaringClassTest and
foo.GetDeclaringClassTest$Foo$BackRef disagree on InnerClasses attribute
at java.lang.Class.getDeclaringClass(Native Method)
at
foo.GetDeclaringClassTest.get_declaring_class_should_not_throw_error(GetDeclaringClassTest.java:20)
