Weld 2.0.0.Alpha2 released

Posted by    |       Weld

Weld 2.0.0.Alpha2 has just been released. Weld 2 is an implementation of JSR-346 (CDI 1.1). The highlights of the new version are:

  • Significant improvement of memory usage. Our benchmarks show that the memory footprint of Weld 2 has been reduced by 50 - 80% compared to Weld 1. This has been achieved mostly by rewriting the metadata layer and separating metadata needed for Weld bootstrap from metadata used at runtime.
  • Concurrent bean deployer and bean validator. These two components speed up Weld bootstrap by leveraging capabilities of multi-core CPUs. The bootstrap time improvement is most significant in large deployments. We plan on reducing bootstrap time even more in future releases.
  • Stuart removed the Javassist dependency entirely and switched to jboss-classfilewriter
  • Around 30 bug fixes, mostly picked from the 1.x branches (most of the credit here goes to Stuart, Ales and Marko)

Furthermore, a new version of the CDI 1.1 TCK has been released. The TCK currently provides a solid coverage (90.60%) of the JSR-346 Early Draft
