Eclipse itself doesn't know about Spring Boot. It's the Spring Tools 
Suite plug-ins that add this behavior.

The Spring Tools Suite launches its Language Server 
(BootLanguageServerBootApp) into a separate JVM from one running Eclipse 
and its that BootLanguageServerBootApp app that runs out of memory
https://github.com/spring-projects/sts4/issues would be the place to 
report issues with Spring Tool Suite plugins.
