    We are glad to announce immediate availability of YourKit Java Profiler 8.0 released on February 13, 2009. It can be downloaded at MOST NOTABLE CHANGES AND NEW FEATURES IN 8.0: ============================================= MEMORY PROFILING: - Snapshot index file accelerates snapshot opening, which makes the subsequent snapshot loadings much faster, as well as allows opening big snapshots on 32-bit workstations by using index file pre-created on powerful 64-bit machine - Class loaders view shows objects grouped by class loader; this view can help solving issues such as leaked loaders - In Class list, retained size estimation for each class is shown immediately on opening the view - Allocation telemetry: ability to profile object allocation without capturing a memory snapshot - Non-serializable objects referenced from serializable objects inspection - Option to transfer memory snapshot of remote application via compressed data stream - Special handling of byte[] and char[] in UI CPU PROFILING: - Callees list - "Own time" column in call tree - "Average time" column in call tree TELEMETRY: - Exception telemetry - Thread state telemetry - Telemetry graphs are now scalable - Ability to change the telemetry buffer capacity J2EE: - "Generic server" option helps integrating with servers not explicitly supported by J2EE server integration wizard - J2EE server integration resolves many problematic cases of e.g. edited/modified scripts which prevented successful integration in previous versions IDE INTEGRATION: - NetBeans 6.5 supported - JDeveloper 11g supported USER INTERFACE: - Table column visibility is now configurable - Overall usability improvements LICENSING: - The profiler agent and controller are are freely redistributable under BSD license MISCELLANEOUS: - FreeBSD supported - Command line tool to control profiling without using the profiler UI; in some cases it can be used instead of the profiler API - Automatic deobfuscation: yGuard and ProGuard supported; RetroGuard support improved - Overall stability and performance improvements See complete list of changes at
  2. After experiencing several crashes while trying to profile an application software that I'm working on, I decided to try out YourKit Java Profiler. I installed the plugin and performed the IDE integration with netbeans 6.5 successfully. However, when I start netbeans after that, I get the warning below: "Warning - could not install some modules: YourKit Java Profiler Integration - The module JBoss Application Server was requested in implementation version "200811100001" but only "200901261116" was found." If I click the "Disable Modules and Continue", netbeans starts, but I don't get the profiler. I'm using Ubuntu 8.10 and sun java jre build 1.6.0_11-b03 is what's default. I don't know how to proceed with the evalution, since it doesn't install...
  3. I don't know how to proceed with the evalution, since it doesn't install...
    1) Go to [url=]support forum[/url] and ask them about this bug. 2) Don't bother with NetBeans integration as it brings very little to the table.
  4. The problem with NetBeans 6.5 should be fixed in maintenance build 8.0.1 which is now available for download at
  5. 8.0.1 solved it!
  6. Congrats ! Most certainly one of the best profiler. IDE integration is just magic : a few clicks and it works. It does not have the fancy graphics other profilers have, but it does not matter too much. Thanks !
