For import/jar breakpoints, how to breakpoint in advance, what about retention across VSCode restarts? #1311

On Linux, I'm debugging a Spring Boot WebApp using spring-web-6.0.6.jar. The jar is located under the user HOME directory...

/home//.m2/repository/org/springframework/spring-web/6.0.6/spring-web-6.0.6.jar

I'm able to trace into framework functions with full source support... that part worked well... was impressed. I can set jar-bound framework breakpoints using F9 after tracing into the framework but...

I now want to set a manual breakpoint within the jar-bound framework but cannot seem to find a way. Is there a way?

More info...

After tracing into the framework, setting a BP with F9, I see the BP is added to the breakpoint window without any function name. They instead appear to be added as <classname>.class and they cannot be edited so they are different from user-specified manual breakpoints.

I tried setting a bp on <classname>.<functionname> but it's not working. Is there a way to manually set a breakpoint in advance on a specific jar-bound framework function?

On top of all the above, if I restart VSCode, it seems my breakpoints within the jar (established by tracing into, using F9) are gone... not retained across restarts.

I'm not in VSCode/Java daily so not urgent for me alone... asking to see if I'm missing something, or maybe others will +1.

Thanks.
