In other programming languages, the compiler produces machine code for a particular system. JVM is a part of Java Runtime Environment (JRE). It converts Java bytecode into machines language. Java Virtual Machine (JVM) is a engine that provides runtime environment to drive the Java Code or applications. What is false about constructor? Explanation: The constructor cannot have a return type. In other words, it is a way to destroy the unused objects. Garbage Collection is process of reclaiming the runtime unused memory automatically. In java, garbage means unreferenced objects. Unused objects are typically removed by the Java Garbage Collector (GC) but in cases where objects are still being referenced, they are not eligible to be removed.

I don't see my application under "Connection" section. Mvn spring-boot:run ="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005 -agentpath:C:\ProgramData\YourKit\2019.1.110.04084DAD\64\yjpagent.dll=disablestacktelemetry,exceptions=disable,delay=10000 With all of it the profiling is pretty much pointless for me. When I click on my application name under "Local Applications" section it appears under "Connection" with after a small delay, but I the CPU time shown when I start CPU Profiling with default sampling option is completely off (significanly smaller than a real time) and when I start CPU Profiling with tracing option time most of time it takes forever and I get an error that tracing is not available or some time it comes and time is significantly higher and most of time taken is shown from. I have upgraded to a new major version supporting JDK11 and now I have major problems.įirst, when I add YKJ agent on server startup it doesn't seem to work.
