Summary0036762: Window personalization list can not be loaded properly due to an error during its sorting
DescriptionWindow personalization list can not be loaded properly due to an error during its sorting.

The list of personalizations for a tab is sorted[1] before returning it to the client.

Since Java 7 Collections.sort uses TimSort. Using a non-transitive comparator for sorting in Java >= 7 will throw the following exception: java.lang.IllegalArgumentException: Comparison method violates its general contract!

And the PersonalizationComparator is not transitive when checking the priority by client.

[1] https://code.openbravo.com/erp/devel/pi/file/4fa54a2fb83d/modules/org.openbravo.client.application/src/org/openbravo/client/application/personalization/PersonalizationHandler.java#l270 [^]

Steps To ReproduceOption A:

** Ask the environment to Support department **

1) Open 'Window Personalization' window and set active every views for user 'Diego' and window 'Product' (there will be 21)
2) Open 'Product' window and click the 'Save View' button on the toolbar. The following error is fired in the log (see attached the full log):

Caused by: org.openbravo.base.exception.OBException: Exception when getting personalization settings for window ADWindow(140) (name: Product)
    at org.openbravo.client.application.personalization.PersonalizationHandler.getPersonalizationsForWindow(PersonalizationHandler.java:254)
    at org.openbravo.client.application.personalization.PersonalizationHandler.getPersonalizationForWindow(PersonalizationHandler.java:98)
    ... 57 more
Caused by: java.lang.IllegalArgumentException: Comparison method violates its general contract!

    at java.util.TimSort.mergeAt(TimSort.java:512)
    at java.util.TimSort.mergeCollapse(TimSort.java:437)

    at org.openbravo.client.application.personalization.PersonalizationHandler.getPersonalizationsForWindow(PersonalizationHandler.java:251)
    ... 58 more


Option B:

1) Attached is patch with a test case that checks if the PersonalizationHandler is transitive. Apply it.
2) Run test.
Proposed SolutionChange the PersonalizationHandler in order to fulfill the Comparable[1] contract.

fixes bug 36762: The comparator to sort window personalizations wasn't complete

  Since Java 7 Collections.sort uses TimSort. Using a non-transitive comparator for sorting in Java >= 7 can throw the following exception: "java.lang.IllegalArgumentException: Comparison method violates its general contract!" depending on the comparisons performed by the comparator.

  The PersonalizationComparator violated the Comparable contract when checking the priority by client between two window personalizations to calculate their position. Now this problem has been solved.
