Andreas blogged about why he likes JRuby even though he dislikes Java.

JRuby is "It's just Ruby" with more than 50,000 tests to ensure MRI compliance. The blog highlights that there is no need to know Java, at all, to run JRuby. Here are some advantages that are described in the blog:

1. JVM runtime optimization
2. Efficient memory usage
3. Native threads to spread work on multiple cores
4. Great garbage collection to make memory usage more efficient
5. JIT and AOT compilation
6. Inegration with Java libraries
7. Running Rails applications on existing Java application servers
8. Documentation and specs
