327 specific error messages (as of version 2.0.0)
The compiler supports 327 dedicated error or warning messages that precisely explain any problem that the compiler has identified in your sources. Each message refers to the paragraph in the OTJLD that is being violated by the problem at hand. The Problems view of the OTDT furthermore offers an option "Go To Language Definition" in its context menu for quickly navigating to this exact paragraph for further reference.

Test Figures

The initial development of compiler and runtime was driven by a test suite of 699 JACKS test cases (2004). This suite has continuously grown and was later converted into a suite of JUnit Plug-in tests. As of June 2011 this suite comprises 2412 unique JUnit tests (part of the tests are executed twice - for different compliance levels, so the total number of tests executions currently if 4550).

For the development of the OTDT original JDT JUnit Plug-in tests are run to check for regressions amounting to 44385 JUnit tests. Additionally, 2367 JUnit tests have been developed specifically for the OTDT.

Thus a full test run currently comprises 51302 tests.
