what is java-templates source?

[Harvey]

The primefaces source is broken into src/main/java and src/main/java-templates. None of the classes from java-templates are in primeafaces-3.5-sources.jar.

Alot of patches I have seen are to classes in java-templates. For example:

--- primefaces.orig/src/main/java-templates/org/primefaces/component/tabview/TabViewTemplate.java 2011-12-14 10:39:25.306764356 +0100
+++ primefaces/src/main/java-templates/org/primefaces/component/tabview/TabViewTemplate.java

However I cant see TabViewTemplate class in the primeafaces-3.5-sources.jar or the build in primeafaces-3.5.jar. So can anyone explain what is java-templates for?

Thanks
