This is what I've done to circumvent this issue. For my project to work, I need the -parameters option and I also like the -preserveAllLocals for debugging.

As IntelliJ accepts a custom ECJ jar, I figured I'd recompile ECJ with the options hardcoded to get around that bug. Unfortunately, the documentation is quite sparse and doesn't show an easy way to build ecj.jar.

I've decided to modify the jar instead! There is a neat tool called Recaf that does just that, decompiles a jar and allow you to easily modify it and repackage it. Neat!

1. Head to mvn repo to download the latest jar
2. Download recaf fat jar and execute it with `java -jar

PID from the threads/process will be different from the host that from inside the container. 

This makes reading thread dump tricky as the thread dump will show the nid of inside the container however you might be checking CPU usage from the host!

To find the mapping of the two, it's easy. Find the PID of the thread/process on the host. 

After this, run `cat /proc/{PID}/status |grep NSpid`. Example : 
```
NSpid:	31144	83
```
