[bug] mixed notation of objects with { } and . lead to null

[andreaTP]

minimal repro:

  @Test
  def parseNestedObjectsWithMixedNotations() = {
    val config = ConfigFactory.parseString("a { b.c { d = 1 } }")

    assert { config != null }

    assertEquals(config.getConfig("a.b.c").getInt("d"), 1)
  }

this will fail throwing a NPE

Bump on this issue. I encountered it adapting configs for lagom.js. I removed the mix notation as a work-around.

Completely forgot to take a closer look at this, thanks for the heads up @mliarakos !
