'ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options

I am using Eclipse plugin "IBM Worklight Developer Edition".

I am trying to debug the adapter procedure code. For that I tried to do some debug configurations but it said Server already running(debug button disabled). So I stopped the server then again tried debug configuration, this time the button was enabled but on console I got "ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options."

Please help me to do debug configuration.

Solution 1:[1]

You must start the server using the "Run" button instead of "Debug". You have set jdwp option in launch configurations and hit "Debug", while hitting "Debug" sets another jdwp option, so you get that error.

It would great if you could edit your question and supply more information...

  • Worklight version
  • Java or JS?
  • The full error exception and trace
  • What is the problem you are trying to debug?
