Regression Gen.nonEmptyBuildableOf and dependent methods since 1.14.3

[satorg]

Consider the following example:

val nestedGen = Gen.listOf(Gen.resize(5, Gen.nonEmptyListOf(Gen.asciiChar)))

Prop
  .forAll(nestedGen, nestedGen, nestedGen, nestedGen, nestedGen, nestedGen, nestedGen, nestedGen) {
    (_, _, _, _, _, _, _, _) => true
  }
  .check()

It usually succeeds on 1.14.3, but almost always fails on 1.15.1 with errors like:

Gave up after only 43 passed tests. 501 tests were discarded.

My guess is that nonEmptyBuildableOf has changed and that made the new implementation less reliable in some cases with a few of non-empty-whatever generators with reduces max size.

UPT: duplicates #708, resolved by #709.

Similar issue: #581.
But it was posted for 1.14.x and it seems things became worse since then.

It appears Erik caught this and fixed it, see #709. It didn't get merged in time to be included in 1.15.1. It will need to be released in the next version, 1.15.2.

so we should close this, then?

[satorg]

I guess yes – looks like the fix in #709 should resolve this issue as well. Thanks for pointing it out.
Looking forward to get it released:)
