Jrockit starts up in windows in a splash and dies

JRockit Version 4.1

Windows 7 Eneterprise

I normally used to click from All Programs > JRcokit Mission COntrol 4.1 and it used to work smoothly without any issues. All of a sudden it started to give up.

I tried to google and someone suggested to invoke like below

C:\Users\aagashe>"C:\Program Files\Java\jrockit-jdk1.6.0_37-R28.2.5-4.1.0\bin\jr

mc.exe" -consoleLog 2>&1 | more

I get error message like the one below.

Any idea what is going wrong ?

It looks like your user settings might be causing the problems for some reason. Try renaming your c:\users\aagashe\.jrmc folder to old.jrmc (or something else if you want to), and then start JRMC again and see if it works better.

I did a search on "

com.jrockit.mc.rjmx.core.connections.internal.ConnectionDescriptorFolderNode initializeFromXml" and found the entry in plugins.xml.

Node has the following value

         point="org.eclipse.core.runtime.adapters">

      <factory

            adaptableType="com.jrockit.mc.rjmx.core.connections.internal.ConnectionDescriptorNode"

            class="com.jrockit.mc.memleak.ui.adapters.MemleakEditorInputAdapterFactory">

         <adapter type="com.jrockit.mc.memleak.ui.IMemleakEditorInput"/>

      </factory>

SO it seems like memory leak in Windows? why it started happening all of a sudden ?

Thanks for that, I would try that tomorrow as for now I need to monitor the app server performance and cannot close current running instance.. I got it working by this command:

"C:\Program Files\Java\jrockit-jdk1.6.0_37-R28.2.5-4.1.0\bin\jrmc.exe" -data C:\OnlyOnMyPC

Running with the -data flag will have the same effect, using new/other user setting. Good that it helped.

Thanks Klara, really appreciate your help. It definitely worked
