[cross-project-issues-dev] Using Java 5 language features in WTP 2.0

On the status call today we agreed to the following policy:

  • Implementations in the “common” component will be restricted to 1.4.x VM levels, which implies Java 1.4 language features (no Java 5 features, such as generics). However, developers can request permission of the PMC to use Java 5 language features on a plugin-by-plugin basis.
  • All other components in WTP are free to use Java 5 language features, and WTP as a project will require a Java 5-level VM in the 2.0 (“Europa”) release and will need to be compiled with a Java 5-level compiler.

 

Maintenance releases on the 1.x lines (1.5.1, 1.5.2, etc.) are unchanged – they are still restricted to Java 1.4 language features and must compile and run on a Java 1.4 JDK/VM.
