Servoy integrates with the Open Source edition of Terracotta and is tested against the "Terracotta 3.7.0 (including Ehcache 2.6.0 and Quartz 2.1.6)" release. The integration should remain functional when new versions of Terracotta become available, as long as tim-api.jar remains 1.3.0 compatible.

Terracotta 3.5.0 introduced a bug that prevented it from working with Servoy. That bug was fixed in Terracotta 3.7.0.
So please use Terracotta 3.7.0 or later. If you need older versions try Terracotta 3.1.1 - 3.4.1.
