/*
Value is always true (counter == 0 || batches.hasNext() || pending.isEmpty(); line#41)
  One of the following happens:
    Operand #1 of or-chain is true (counter == 0; line#41)
      Left operand is 0 (counter; line#41)
        Range is known from line #35 (counter == 0; line#35)
    or operand #2 of or-chain is true (batches.hasNext(); line#41)
      One of the following happens:
        'batches.hasNext == true' was established from condition (counter > 0 && batches.hasNext(); line#27)
        or 'batches.hasNext == true' was established from condition (counter == 0; line#41)
    or operand #3 of or-chain is true (pending.isEmpty(); line#41)
      According to hard-coded contract, method 'isEmpty' returns 'true' when size of pending == 0 (isEmpty; line#41)
        Left operand is 0 (pending; line#41)
          Range is known from line #41 (counter == 0; line#41)
