java.lang.StackOverflowError during hover

[nocquidant]

Hi, just installed the last extension version 0.18.0.
Thank you, but java exceptions appear a lot the console...

Are you able to share the file you're opening that's causing this error?

[bioball]

I can reproduce the error with this snippet:

import "pkl:reflect"

class Foo {}
local classes = new Listing {
    Foo
}.toList()

function isClassOrSubclass(value: Any, clazz: Class?) =
  if (clazz == null) false
  else if (value.getClass() == clazz) true
  else
    isClassOrSubclass(value, reflect.Class(value).superclass?.reflectee)

function check(a: Any) = classes.any((it) -> isClassOrSubclass(a, it))

Trigger hover on isClassOrSubclass on the last line.

I think this is the file:

// Template to produce _backend.conf file for terraform
backend {
	profile = "_"
	bucket = "_"
	region = "\"eu-west-3\""
	dynamodb_table = "_"
	workspace_key_prefix = "_"
	key = "\"terraform.tfstate\""
}

// Template to produce _variables.tf.json file for terraform
variables {
	variable {
		application_id {
			description = "The application id (a short name)"
			type        = "string"
			nullable    = false
		}
		application_name {
			description = "The application name"
			type        = "string"
			nullable    = false
		}
		environment {
			description = "The environment name"
			type        = "string"
			nullable    = false
		}
	}
}

output {
  files {
    [".pkl/_backend.conf"] {
      value = backend
      renderer = new PropertiesRenderer {}
    }
    [".pkl/_variables.tf.json"] {
      value = variables
      renderer = new JsonRenderer {}
    }
  }
}
