Deadlock with Spring LSP in Eclipse 4.23 with STS 4.23 nighlies #729
Description
When running a large workspace with many spring project for a while, specially if the machine was resumed after sleep, working Java classes cause the deadlock. The java class operation which cause this deadlock is trying to ctrl + hover over a typename to get the hyperlink list. With this versions the Java element hyperlink list is also slow because the language server takes time to respond for hyperlink commands.
