v1.41.0 has deadlock problem

[wwingyou]

I'm using Jdtls in neovim with vscode-java-test and java-debug module. After upgrading from v1.3x.x, starting jdtls has been significantly slower sometimes. The log shows that there're deadlock problem.

This problem don't occurs in relativley small projects. I haven't tried other types of projects, but there's problem with spring boot project.

Here's log and build.gralde file.
