Changes in build 4004

  • Memory profiling: Class list view: retained size estimation is immediately shown for each class. Of course, you still have an option to run retained size calculation to obtain exact sizes.
  • Thread status telemetry: now you can click at certain time point in the upper table to see stack traces
  • IDE integration: NetBeans 6.5 Beta supported. Known issue: profiling J2EE targets from within the IDE may not work. This will be fixed in nearest builds. As a workaround, start profiling via the profiler's J2EE integration wizard.
  • IDE integration: JDeveloper 11g supported. Known issue: profiling J2EE targets from within the IDE may not work. This will be fixed in nearest builds. As a workaround, start profiling via the profiler's J2EE integration wizard.

Changes in build 4000

  • New feature: exception telemetry
  • New feature: thread status telemetry
  • UI: locally running profiled applications are immediately listed on the Welcome screen
  • Memory profiling: up to 50% (32-bit) and up to 30% (64-bit) faster retained size calculation, comparing with 7.5.x. This improvement is especially important in Class list view.
  • UI: stability improvements: fixed occasional exceptions that might happen after closing a snapshot
  • Windows 64-bit: to achieve better performance and user experience, the profiler UI will automatically launch on a 64-bit JRE

AWARDS
JDJ Editors' Choice Award Winner YourKit Java Profiler received the Java Developer's Journal Editors' Choice Award.
"I had to collect data about a memory leak that happen over several hours of time in the production server. Using other profilers this was not possible since they kept on crashing. Using YourKit this was amazingly easy. It just ran in the background and I gathered statistics at certain moments in time and then compared them against each-other. YourKit is a really nice profiler and I use it now."
