Sujithra Rajan updated OPENNLP-1519:
------------------------------------
    Description: 
Two tests
 * `opennlp.tools.dictionary.DictionaryAsSetCaseInsensitiveTest.testEquals`
 * 
`opennlp.tools.dictionary.DictionaryAsSetCaseInsensitiveTest.testEqualsDifferentCase`

uses HashSet for entrySet while initializing the 'Dictionary' and thus the 
order is not constant all the time.

This was found by using the 
[NonDex][https://github.com/TestingResearchIllinois/NonDex] tool.

Encountered the following error messages:
{quote}org.opentest4j.AssertionFailedError: expected: <[1a, 1b]> but was: <[1b, 
1a]>

opennlp.tools.dictionary.DictionaryAsSetCaseInsensitiveTest.testEquals(DictionaryAsSetCaseInsensitiveTest.java:121)

at 
opennlp.uima.dictionary.DictionaryResourceTest.testDictionaryWasLoaded(DictionaryResourceTest.java:76)
{quote}
 

The fix is to change HashSet to LinkedHashSet so that the iteration order 
remains stable all the time. 

Assertion statement of 'testDictionaryWasLoaded' was modified to match the 
exact ordering of dictionary.dic.

 

{*}REPRODUCE{*}:

```

mvn edu.illinois:nondex-maven-plugin:2.1.7-SNAPSHOT:nondex 
-Dtest=opennlp.tools.dictionary.DictionaryAsSetCaseInsensitiveTest#testEquals

```

 Can I proceed and create PR ?
