IV25851: LINKEDHASHMAP DOESN'T REFLECT CHANGES IN THE ENTRYSET

APAR status

• Closed as program error.

Error description

• Error Message: The failing scenario is as follows:
  1) Create a LinkedHashmap containing 10 instances of a
  particular value
  2) use the values() method to retrieve a 'Collection' of the
  values in the table
  3) use the entrySet() method to retrieve a 'Set' of the entries
  in the table
  4) Remove one of the entries from the entrySet
  5) Get an iterator over the values 'Collection' and check that
  it now contains only 9 instances of the value.
  Step 5 fails with the symptom that it now contains 10 instances
  of the value.

  Stack Trace: N/A
