Plugin recompilation check panics with inline-java

When building https://github.com/tweag/inline-java with the beta release of ghc 8.6.1, I'm getting a panic like the one in #15475 (closed).

The fact that ghc tries to locate a library in {{/nix/store/5zgi3snmw1iq704jjaildk7x333s10cw-gradle-4.9/lib}} to check for recompilation makes me think that this is an actual bug in GHC. But I would be happy to get some assistance to confirm this.

I tried disabling recompilation checking by defining the plugin as:

plugin :: Plugin
plugin = defaultPlugin
    { installCoreToDos = install
    , pluginRecompile = purePlugin
    }

but the error persists.

This is what my dependencies look like in stack.yaml:

packages:
- .
- jni
- jvm
- jvm-batching
- jvm-streaming
- examples/classpath
- location: singletons
  extra-dep: true
- location: criterion
  extra-dep: true
- location: polyparse-1.12
  extra-dep: true

I'll see to share my modifications to singletons, criterion and polyparse, if necessary. I just fixed some dependency bounds and added MonadFail instances.
