Can we add a unit test for this?

[halostatue]

Please rebase against main; I modified the CI behaviour some because truffleruby+graalvm-head has turned out to be fairly unstable and we can’t see the results of the tests based on this.

@halostatue I have rebased it against main. To write a valid test case, We need to fix the reader(https://github.com/halostatue/minitar/issues/46). I will fix the reader first and then update the test case here.

@bv-vijay Did you ever get a chance to fix the Reader issue, or can you provide a sample tarball that exhibits the error on #46 so that I can examine it?

[halostatue]

We have a resolution for #46 with #49. Based on investigations, I will be merging this after #49 and then I will release 0.12.
