clojure.test is assertion highlighting does not work in remote nREPL

[thheller]

When I connect to a remote nREPL (eg. lein repl) and Run test under caret in REPL I get warnings for each is assertion in that test. The warning is printed as red text into the REPL output window.

(deftest something
  (is (= 1 1)))

causes

Error handling response - class java.lang.IllegalArgumentException: Argument for @NotNull parameter 'path' of com/intellij/openapi/vfs/impl/local/LocalFileSystemBase.findFileByPath must not be null

and repeats that warning for each additional is, it does not matter if the is succeeds or not.

The highlighting Cursive usually shows for is does not work.

I'm having the same issue, except also in a local REPL. The issue suddenly appeared today.

I am pretty sure that this is not a problem of namespace mismatch as reported here: After a while of trying to locate the error I started to check out earlier versions that tested without issue back in the day, and they're suddenly having the same problem. I tried with taged versions of the project as far back as November, and it's still there.

Other projects, however, do not appear to have it, so there does seem to be something project specific, but I can't get a fix on it.

I don't see anything particularly helpful in the logs, but here is an entry anyways (they are all identical):

I would be glad for any help resolving this issue.

Like I just mentioned in #1258 (comment), this is no longer a problem for me by having upgraded to IntelliJ 2017.3 and Cursive 1.6.2-2017.3. Perhaps this also solves it for you and this issue can potentially be closed?
