@m2kar This is strange.

Could you share the output of?

docker run --rm -it -v /tmp:/tmp -v $(pwd):/app:rw -w /app -t ghcr.io/joernio/joern:nightly java -version

docker run --rm -it -v /tmp:/tmp -v $(pwd):/app:rw -w /app -t ghcr.io/joernio/joern:nightly echo $JAVA_HOME

As a workaround, start the bash shell and then type joern

docker run --rm -it -v /tmp:/tmp -v $(pwd):/app:rw -w /app -t ghcr.io/joernio/joern:nightly /bin/bash
joern

[m2kar]

Here are the output of the shell commands:

1.

@m2kar Could you try it on a recent version of Linux with sufficient memory?

[m2kar]

The memory is sufficient.

$ free -m
              total        used        free      shared  buff/cache   available
Mem:          17275        3066        9277          56        4930       13855
Swap:          2047           0        2047

The linux version:

[prabhu]

@m2kar Kernel 4 is quite old. Do you have ubuntu 22.04?

[m2kar]

I try on another operation system, and this docker works.

$ lsb_release -a

There may be some incompatibility within the older version of Docker or the older version of the Linux kernel.
