We've been using jboss-aop for past 6 months or so without any issues, except for one
weird problem that crops up now and then.
Whenever a class to be aspectized contains a variable whose name is "org"
(without quotes), then the aspectization fails with the error stack pasted below. Pls See
sample code.
Mostly, when the source code is in my control i can change the variable name to
"org1" or something and proceed, but sometimes changing the variable name can be
quite a cumbersome process if source is not owned.
Is this some known issue ? I searched the forum and googled but didnt find anything.
We use load time weaving.
AOP version 1.5.3 GA
Jboss - 4.0.2
JRockit - jrockit-R26.4.0-jdk1.5.0_06
Steps to reproduce : include following package in jboss-service.xml of
jboss-aop-jdk50.deployer, and invoke m1 from a JSP or some place.
package com.integral.admin;
public class Test
{
private static String org="Fail";
public void m1()
{
System.out.println("Dummy");
}
}
If variable name is changed from org to org1 it starts working. Weirdly enough, changing
the package also fixes the problem. So, it looks to be combination of package name and
variable name being org.
