Java Profilers for a Spring Boot application which is using too much memory

Hi, just a quick question: are there any recommended tools?  We are using Java 17.
Looking at a few already, IntelJ Profiler and Java Mission Control.  Others seem to require a license or are older.  
(Thanks in advance)

Is your goal to locate the source of excessive memory consumption?

VisualVM has help me find memory leaks (sticky references, resources that never get closed, unremoved thread local storage for pooled threads, etc.).  Depending on what you are trying to find, it may help.

I am yet to need anything more than VisualVM to find memory leaks. In my case it's usually some kind of object creation in a loop that gets out of hand, and that usually turns up in VisualVM as a collection with a lot of things in it.

Yes, looking at an application that is using too much memory.  
Many thanks, I'd taken Visual VM off my list of candidate tools, but will now look into it.

I worked in a shop that was too cheap to buy tools and had to use the stuff that comes in the JDK.

Took me several days to discover that the Oracle JDBC driver I was using had neither FIFO nor LIFO, but LIFI (last-in, FOREVER in). Test runs would take about 2-1/2 days each before critical mass was reached and the system blew. And, unfortunately, the data being traversed would hit that easily in production.

Once I discovered that fact, I found it was actually in Oracle's documentation. Down the stairs in an unused bathroom behind a locked filing cabinet bearing a sign marked "Beware of the leopard". But as a general rule we expect drivers to limit themselves. so I missed the faint note and had to discover it the hard way.
