VisualVM freezes for several minutes before showing the profiling info #567
Description
Describe the bug
VisualVM freezes and becomes unresponsive when monitoring certain Java applications for extensive period of time before actually showing the profiling info. This occurs consistently when trying to interact with the application views within VisualVM, and no specific error message is displayed in the UI.
Then, in 6-10 minutes it suddenly shows the profiling data
Despite this, some other java apps like Intellij Idea and VisualVM itself are displayed without any lags.
To Reproduce
- Start VisualVM.
- Attach VisualVM to a running Java process, such as java Test.
- Click somewhere in the left menu.
- VisualVM becomes unresponsive with no error feedback.
- After some time, around 8 minutes in average, the app wakes up and shows the info.
'Test' code:
public class Test {
public static void main(String[] args) {
System.out.println("Hello, World!");
while (true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
While looking at VisualVM process itself works fine:
When I try to open any local applications, the loader is going back and forth indefinitely:
Until I try to click elsewhere on the window, when it freezes:
And after 6-8 minutes it wakes up and works as normal:
Expected behavior
Expected VisualVM to monitor and interact with Java applications without becoming unresponsive or freezing for several minutes
