Just to add , I am using oracle-jdk/22.214.171.124/linux-x64/bin/java and byteman version is 2.1.2 .
tools.jar is also from oracle-jdk/126.96.36.199/linux-x64/lib location
There are several reasons why the agent might fail to initialize. The problem you are seeing here will be happening in the JVM that you are trying to install the agent into (i.e. process 3411 in the above report).
Could you please start that JVM with -Dorg.jboss.byteman.verbose on the command line and then report any Byteman messages or exceptions that are posted to System.out or System.err.
Also, it would be better if you upgraded to the latest Byteman release (3.0.6). This is 100% backwards-compatible with the one you are using and it includes quite a few bug fixes (n.b. I very much doubt this is what is causing whatever problem you are seeing but it is worth using this release just in case it helps with other problems).
I am trying to first test on windows now.
(1) I started one main java class from IntelliJ community edition version 2016.1.2b. JDK 64 bit 8 is being used inside IntelliJ
(2) Once above main class was started successfully, I fired jps command in windows prompt which showed me process Id as 13544(This Is Intelli J process id as when I try to kill 13544, I got a pop up of exiting IntelliJ..not sure how to get Java process Id running inside Inteli J ?
(3) Then I fired below command form windows command prompt :-
C:\FAST\JDK64\188.8.131.52\jre\bin\java -classpath "C:/Users/gaurav/byteman.jar";"C:/Users/gaurav/byteman-install.jar";"C:/Users/gaurav/tools.jar" org.jboss.byteman.agent.install.Install -h localhost -p 12345 -Dorg.jboss.byteman.verbose 13544
(all byteman jars are 3.0.6 version jars and tools.jar I also from JDK 64 bit 8 )
But I am getting below error:-
com.sun.tools.attach.AttachNotSupportedException: Unable to attach to 32-bit process running under WOW64
When I googled , I found article :- JVM Monitor documentation which says :-
If you see the additional message "Unable to attach to 32-bit process running under WOW64", your application is running with 32bit Java while using 64bit Eclipse on Windows. Either using 64bit Java for your application or using 32bit Eclipse solves the issue
But, My Intelli J is using Java 64 bit 8 , my command prompt command is also making use of jdk 64 bit 8. Not sure what is the error? Is it that IntelliJ which I am using is 32 bit and community edition do not support 64 bit IntelliJ ??
or may be I am injecting agent into proess id of IntelliJ and not of my java program running inside IntelliJ ???
