Description Frederic Fusier CLA 2006-06-08 10:51:25 EDT 
If you use -Dordering=3 system property to change tests order while running JUnit JDT/Core all tests, then some tests are failing and model tests do not finish.

The "ordering" system property specified in launch configuration VM arguments change tests order in following manner:
1: alphabetical ascending order
2: alphabetical descending order
3: random order using JDT/Core version for seed
4: random order using time for seed
n: random order using given 'n' value for seed

This option simulates a VM which would sort methods differently than usual ones...

Failing tests using Sun 1.5.0_08 VM

Note that tests seem to be also VM dependent not only for tests order. Some tests expected results used Map which may be ordered differently on other VMs or other versions.
This must also be fixed...
Comment 2 Jerome Lanneluc CLA 2006-06-09 06:19:03 EDT 
Entered bug 146215 for the order problem due to the different Map implementation.

ClasspathInitializerTests issue does no longer occur in HEAD stream => just force tests sort in maintenance stream
