The changes to the Java tools to support J2SE 5.0 (aka 1.5) are proceeding nicely. The Eclipse Java compiler now handles generics, enhanced for loops, and hexadecimal floating point literals (at this point we're passing 96.8% of the JCK1.5 compliance tests). The other language additions - enumerations, annotations, static imports, varargs, autoboxing - make it past the parser, but are not yet being processed any deeper than that. Support for these other new language features will be introduced in future 3.1 milestones.
In order to work with any of the new language features you must set the Java project's compiler compliance level to 1.5 (Java Compiler > Compliance and Classfiles > Compiler compliance level > 1.5) and configure the Java build path with the system libraries from an installed 1.5 JRE.

Könnte also wohl noch ne ganze Weile dauern, bis die das endlich mal fertig haben ...
