XRebel 2.0 Beta is available for download! The new version includes profiling capabilities and it is now possible to get an overview of performance breakdown in a single HTTP request. The cool part is that XRebel shows only the minimal relevant information by filtering out a lot of irrelevant stuff. I have tested the new version with a lot of different enterprise-grade applications, including Atlassian Jira, Magnolia CMS, Liferay Portal, eXo Platform... and it works just great!
The greatest feedback so far was that the tool provided the ability to monitor JPA queries and the subsequent JDBC invocations in one go. With the new version, XRebel is turning into a real profiler, yet simple and powerful.
