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

I was cleaning up my mailbox and saw this.  You will be interested to know that PDE supports specifying and compiling against specific "Execution Environments" (see for more information).  All plugins should set their Execution Environment to ensure that they are compiled and run correctly.

[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.
