NetBeans slows down on debugging

[ananyahk]

Apache NetBeans version

Apache NetBeans 15

What happened

When I started remote debugging on NetBeans, on clicking on attach debugger, NetBeans froze for 15 or more minutes and was taking enormous time to execute the line where the breakpoint was placed. It then threw the issue saying: OutOfSpace Memory- Java Heap. It threw this exception: 2022-09-19T08:12:53 1663589573578 353 global 1000 46

Try to delete all your breakpoints and repeat test. It's must be faster
