[GitHub] [netbeans] thurka opened a new pull request, #5909: lower the OS level memory consumption of NB LSP

thurka opened a new pull request, #5909:
URL: https://github.com/apache/netbeans/pull/5909

NB LSP process is different from startd IDE, since it is not a major application user is using. It runs in parallel to major IDE probably VSCode and also in parallel to other installed extensions and LSP servers (potencialy starting another java process). For that reason it is desirable to use different JVM settings from NetBeans IDE. This PR tries to lower NB LSP memory consuption as seen by OS.

- sets maximum Java heap size
- configures the heap to grow, shrink, and give memory it isn't currently using back to the operating system

Current settings mimics the ones used by RedHat's LSP for VSCode, which seems like reasonable start. We expect that the settings can be changed based on the user's feedback.
Identical recommendation is also mentioned in the following [document](https://developers.redhat.com/blog/2017/04/04/openjdk-and-containers).

   Perfect, this can help in VSCode use case when VSNetBeans is one of LangServers running in background on user machine. This is a little bit different than running full NetBeans IDE which is user _dominant application_ on desktop.

   +1 for using a non-concurrent parallel GC, this is usually the right choice for throughput maximizing background processes.
   
   `-XX:GCTimeRatio=4` will allow the JVM to use up to 20% of the execution time for GC (`1/(1+N)`).  I suppose this is done to reduce shrink/grow hysteresis.
   
   Worth keeping an eye on it to check if this is causing any trouble. Memory on the client is cheap. In the cloud it depends on what service you are running on. Some give you memory on a per-core basis etc.
