Hi, Some people ran 1.5.x core tests in parallel with JUnit/Surefire parallel support and the problems they had were related with setting current Locale with Locale.setDefault(), i.e. JVM wide. Some tests expect specific i18n-ized results and due to changed Locale they failed.
Improvements in this area for 1.4.x wont be done but you can provide patches for 1.5 if there are no API breaks and for 6.0 with API changes.
