Some hints:
- You can use an empty param in
initializeto reduce its influnce, as sometimes incorrect parameters may affect server's behaviour - Make sure jdt.ls starts successfully and runs well
- Make sure your code can read jdt.ls's response correctly

Yet, empty request is working, I found from byte data covert error, the byte count is error. now, this is working
If it works now, you can close this issue. If you still have problems (eg. the byte count error), you could check whether you open jdt.ls' stdout in binary mode or not.
jdtls program is python, use other language do process launch start not equal can write(frame not working). should wait can read jdtls befor do write any request to stdout.
The features only for jdtls，It won't happen from cxx or python
