This looks like an issue in eclipse.jdt.ls, let's use the upstream jdt.ls issue to track it.

[PiotrRaszkowski]

It is closed but still happen:

And started to happen when I added:

require('jdtls.dap").setup_dap()

to on_attach function.

[PiotrRaszkowski]

OK, problem solved with this config:

jdtls.setup_dap({ hotcodereplace = "auto" })
						require("dap").configurations.java = {
							{
								type = "server",
								request = "attach",
								name = "debug (attach) - remote",
								hostname = "127.0.0.1",
								port = 5005,
							},
						}
						jdtls.setup.add_commands()
