VisualVM - not supported JVM

Question

Hello Community,
   Related to this post: https://forums.oracle.com/message/4800072
I thought I'd start a new thread since I can't comment the one above.
1) I have visualvm *32 install
2) Monitoring a 64 bit jvm app locally
3) Changed "visualvm.conf" jdk home to 64 bit 1.7
4) I still get the same issue.

Any thoughts on resolving this issue?

Hi,
as you can see, you are running VisualVM on 32bit JVM
1.6.0_20; Java HotSpot(TM) Client VM (16.3-b01, mixed mode, sharing)
You don't need to unistall 32bit JVM. Just tell VisualVM to use tour 64bit JVM.
One way is to use --jdkhome command-line switch.
visualvm_13\bin\visualvm.exe --jdkhome <path_to_64bit_JVM>
If you want to change it permanently, you can edit
visualvm_13\etc\visualvm.conf
uncomment and edit netbeans_jdkhome entry to point to your 64bit JVM.
HTH,
Tom
