Spring Boot Tools for VS Code shows unhelpful/incorrect warning
Expected Behavior
Spring Boot Tools should show a more informative warning when Java components are missing, or not show a warning at all if functionality is not actually affected.
Current Behavior
Currently, Spring Boot Tools will show the following warning message if the jmods component for Java is not installed, even if JAVA_HOME and/or PATH are pointing to the correct JDK location:
JAVA_HOME or PATH environment variable seems to point to a JRE. A JDK is required, hence Boot Hints are unavailable.
Installing the jmods component causes the message to go away. (eg, on my CentOS 8 system that involved installing the java-11-openjdk-jmods package)
Context
The warning message is confusing, as the problem is not with JAVA_HOME or PATH at all, and results in a lot of wasted time trying to figure out what is wrong.
This has been reported here multiple times by other confused users (#576 and #347, for example).
Despite the warning, there doesn't seem to actually be any issues with the extension when jmods is not installed, unless I misunderstand what "Boot Hints" are -- I can't seem to find any documentation that actually mentions that.
If functionality is not affected, the warning should not be shown, otherwise the warning should be updated to explain what is actually being complained about.
Hey @Herohtar, yeah, I agree, this needs some improvements. I will add it to our backlog for one of the next releases.

This is good news. Thanks!

The functionality that would be affected is not everything but only the live hover hints that show information about live beans. So this may be something that isn't easy to spot (i.e. most of the functionality will still work and many folks may not care about the live hovers to notice their absence).
This is just for clarification, but I think we all agree the warning can be improved.
