Description iformanek 2005-10-25 11:29:49 UTC 
I'm attaching an extracted IDE log (NB5.0 beta, profiler M9, Java 1.5.0_04-b05)
showing the same problem. I thought that running NetBeans with bytecode
verification off should help, but it didn't.

My netbeans.conf:

netbeans_default_userdir="${HOME}/.netbeans/5.0beta"
netbeans_default_options="-J-Xms256m -J-Xmx256m -J-XX:PermSize=64m
-J-XX:MaxPermSize=64m -J-XX:NewRatio=3 -J-Xverify:none -J-ea"
netbeans_jdkhome="D:\java5"

The method I was trying to profile contains ILOG JViews method calls. JViews'
jar file is obfuscated bytecode, by the way.

Below a simple 2 class test case using nothing but String and 
System.out.println(). The test case produces the same error, 100% repeatable, 
when using part of application profiling on TestAClass.main().

#################
package com.anca.test.nb;

public class AClass
{
    private String m_state;
    
    public static AClass EFFICIENT = new AClass("Set of parameters producing 
special case of AClass")
    {
        public String toString()
        {
            return "AClass state:\n\tState of special AClass instance";
        }
    };
    
    public AClass(String arguments)
    {
        m_state = "result of some alrogrithm on " + arguments;
    }
    
    public String toString()
    {
        return "AClass state:\n\t" + m_state;
    }
}
######################
package com.anca.test.nb;

public class TestAClass
{
    public TestAClass()
    {
        AClass generic = new AClass("Some generic AClass constructor 
arguments");
        AClass efficient = AClass.EFFICIENT;
        System.out.println(generic);
        System.out.println(efficient);
    }
    
    public static void main(String[] args)
    {
        TestAClass tst = new TestAClass();
    }
    
}
Comment 3 williamn 2006-02-03 01:05:04 UTC 
In terms of issue priority, please consider that the occurrance of this error 
produces invalid profiling results.

The resulting profiling snap shot does not provide any node 
for "AClass.toString()". The tree opens from AClass.init() directly to lower 
level methods.

I will attach a screen shot of the CPU call tree and Console output of the 
redefinition error of AClass (messages.log does not contain the class name).

Comment 5 Tomas Hurka 2006-02-03 09:35:16 UTC 
I cannot reproduce it. See attached screenshot. There is no JVMTI Error 62 and AClass.toString() is there. 
Please attach your messages.log anyway.

I am using Netbeans 5.0 RC2 and Profiler 5 RC2 running on Java HotSpot(TM) 
Client VM 1.5.0-b64.

netbeans.conf:
netbeans_default_options="-J-Xms500m -J-Xmx750m -J-XX:PermSize=32m -J-
XX:MaxPermSize=96m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true -J-

Comment 11 Tomas Hurka 2006-02-06 08:23:30 UTC 
You are using unsupported JVM version. You need JDK 1.5.0_04 or newer, see 
http://profiler.netbeans.org/docs/help/vms.html for more information about supported JDK versions.
Comment 12 williamn 2006-02-07 00:18:28 UTC 
Thanks! I downloaded jdk1.5.0_06 and Part of application profiling works as 
expected now. I guess, I should have RTFM more closely!

The download pages may benefit from stating the profiler jdk requirement at an 
earlier stage. Drilling down the pages, I noticed the "jdk1.4.2 or higher" and 
assumed that 1.5.0 would fit the bill.
