Since a few days VisualVM doesn't work very well.
I don't know why monitoring CPU and Sample are not avalables.
Thank you.

I found this "not issue" ;)
It doesn't work because java app was running from eclipse and i didn't use jre (in eclipse) from jdk.
I modyfied this and it works.

I can't see the "Java Profiling" options in my IntelliJ (see screenshots) and I am not able to launch my Java Spring app with any profiler.
I'm on MAcOS Big Sur, running this version:

I need to add my installed Java 11 version to the project settings, because of this error (Error:java: invalid source release: 11).
When i go to project structure -> Project settings -> Project there it just shows Java 1.8.
When i try to add "java-11-openjdk-amd64" it fails with the reason "The selected directory points to a JRE, not a JDK.".
java -version
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.4+11)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.4+11, mixed mode)
The java application is available in the Java Runtime Environment (JRE). The fact that java is available in version 11 does not necessarily mean that the Java Development Kit (JDK) is also installed for version 11. However, IntelliJ needs the JDK which includes tools like the compiler javac.
In order to use Java 11 in IntelliJ, you need to install the Java 11 JDK.
For example on Ubuntu you can do that by executing:
sudo apt install openjdk-11-jdk
my plugin project can't find any java classes.
How can I make my project compile again?

I figured it out.
Somehow the "project sdk" was broken.
I set it up freshly while I was figuring it out.
But somehow deleting it and creating it a second time fixed it.
I'm using Ti Studio on Win7, and my project builds and works when I have my Android plugged in via USB and I run using "Android Device".
However, when I try to buid it for distribution I get:
[ERROR] Program launch failed. Unable to locate Java VM. Please set JAVA_HOME environment variable.
I have looked at this thread which describes a similar problem, and verified that JAVA_HOME is set:
+>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.6.0_29
Also, in Ti Studio I have verified that Preferences->Studio->Platforms->Android has the "Android SDK Home" set to the path where Android SDK is installed.
Can anyone guide me on what else I need to do to fix this?
Thanks!
UPDATE FOR ANAND
+>javac -version
javac 1.6.0_29
+>java -version
java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)
Did you read System Requirements?
From Documentation:
For Windows, the 32-bit version of Java JDK is required regardless of
whether Titanium is running on a 32-bit or 64-bit system.
Try to install additional 32bit version of Java (without removing the 64bit) and set the system variable.
You may refer this answer.
Hope it helped you
Configure environment variables as mentioned here and JDK must be 32 bit

You have the wrong JDK. You need to use the OracleJDK as specified here.
