java.lang.ExceptionInInitializerError during pod cleanup
Problem Description
When using boot-tools-deps and boot-test, sometimes a java.lang.ExceptionInInitializerError will occur after the test has completed.
I don't know if this is specific to boot-tools-deps and boot-test, but that's where I came across the error and can reproduce it.
Steps to reproduce
git clone https://github.com/grzm/ex.boot-tools-deps-alt-test
cd ex.boot-tools-deps-alt-test
boot deps -Q test
On occassion, I'll get the following stacktrace (a full example is also provided in the repo). Over the course of 10 runs, I'll see it at least twice, if not more often.

From a first glance, it looks like something happens to the stream opened for reading Clojure in the LispReader.
Because things in boot run concurrently in pods, I feel there is some resource contention going on on the sources or build.boot itself.
I might be completely off of course :smile:
Just wanted to say that I hit this too, occasionally. The exception is the same, Caused by: java.io.IOException: Stream closed, compiling:(clojure/core_instant18.clj:15:1) and so on.
It doesn't happen with every project, in fact I have only seen one project yet where this happens (but it happened a few times there already). I use boot-test to test it and run (clojure.spec.test.alpha/instrument (clojure.spec.test.alpha/enumerate-namespace 'my.namespace)) before running the tests.
