In the current implementation, the workspace directory for Eclipse JDTLS is generated using a random UUID for every invocation:

ws_dir = str(PurePath( MultilspySettings.get_language_server_directory(), "EclipseJDTLS", "workspaces", uuid.uuid4().hex, ) ) 

Two directories are created inside ws_dir:

data_dir = str(PurePath(ws_dir, "data_dir")) dtls_config_path = str(PurePath(ws_dir, "config_path")) 

Shouldn't workspace directories be consistent across invocations for the same project?
