Java reflection features allow the use of Java libraries directly from Tea code.
Intended to be easily extended in Java. For example, Tea supports relational database access through JDBC, regular expressions through GNURegexp, and an XML parser through a SAX parser (XML4J for example).
Tea is a proprietary language. Its interpreter is subject to a non-free license. On the other hand, a project called "destea", which released Language::Tea in CPAN, provides an alternative to the proprietary interpreter, by generating Java Code based on the Tea code.
There's an open source compiler, TeaClipse, that uses a JavaCC-generated parser to parse and then compile Tea source to the proprietary Tea bytecode. The author of TeaClipse has expressed interest in enhancing TeaClipse to produce Java bytecode.
