Description Alexander Kouznetsov 2007-09-03 21:34:05 UTC 
Remote attach for AnagramGame application (Memory Liveness, Record Stack Traces, each 20 object allocations) from

Product Version: NetBeans IDE Dev (Build 200709030000) 
Java: 1.6.0_02; Java HotSpot(TM) 
Client VM 1.6.0_02-b05 System: SunOS version 5.10 running on x86; ISO646-US; en (nb)

to

Java: 1.6.0_02; Java HotSpot(TM) Client VM 1.6.0_02-b06 
System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb)

using

C:\Work\Temp\RemotePack\bin>profile-16.bat -jar C:\Work\Temp\RemotePack\bin\anagrams.jar

sometimes produces the following ClassCastException on Profiler side:

java.lang.ClassCastException: com.sun.tools.profiler.wireprotocol.Response cannot be cast to
com.sun.tools.profiler.wireprotocol.VMPropertiesResponse
        at com.sun.tools.profiler.ProfilerClient.connectToServer(ProfilerClient.java:1445)
        ...

This issue is random (~15% reproducible)

Comment 2 J Bachorik 2007-09-24 13:17:41 UTC 
as this issue is very difficult to reproduce i added an error reporting code that identifies the request/response
mismatch and will print additional details about the response, essential to pinpointing the erroneous code.
Comment 3 J Bachorik 2007-09-26 06:57:53 UTC 
i'm marking this incomplete till we can get logging data showing what exactly is causing the request/response mix-up
Comment 4 Tomas Hurka 2007-09-26 09:23:31 UTC 
Please also use 
-Dcom.sun.tools.profiler.wireprotocol.WireIO=true 
for both profiled application and netbeans.

Using direct connect i got:

SEVERE: Received org.netbeans.lib.profiler.wireprotocol.Response(NO TYPEOk, yes) instead of VMPropertiesResponse

Comment 6 _ hair 2007-10-15 10:52:50 UTC 
sorry. (direct connect & beta2)
Comment 7 Alexander Kouznetsov 2007-12-04 17:55:56 UTC 
Removing incomplete flag due to user comment.
Comment 8 Alexander Kouznetsov 2007-12-04 18:57:20 UTC 
However I was not able to reproduce it profiling from

Product Version: NetBeans IDE 6.0 (Build 200711261600)
Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05
System: SunOS version 5.10 running on x86; ISO646-US; en (nb)

to

Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05
System: Windows XP

Probably due to low reproducibility
Comment 9 J Bachorik 2008-07-17 08:43:29 UTC 
I still can not get the error state. Closing this issue as "works for me". If you will experience this problem again,
please reopen the issue.
