LSP4E is specifically meant to intergrate with the Eclipse IDE. If you need a lower-level Java API to deal with LSP messages efficiently, please see LSP4J project. It's been used by several Java clients (this Eclipse project, NetBeans, IntelliJ) and servers (Java with JDT-LS, Microprofile, Jakarta EE, LemMinX for XML...).
