Changes in YourKit Java Profiler 8.0.31 from 8.0.30

• Linux: added support of Linux kernel 3.x, which is necessary to properly detect available system capabilities

Changes in YourKit Java Profiler 8.0.30 from 8.0.29

• IDE integration: NetBeans 7.0 supported
• IDE integration: improved NetBeans plugin installation on Windows Vista and Windows 7. Previously, the IDE integration wizard might fail if NetBeans was installed in a protected directory such as "Program Files" due to Windows User Access Control (UAC). Now, appropriate UAC prompt is shown when necessary, letting the wizard succeed.
• Problem solved: snapshots of some OpenJDK versions might not open due to incorrect object size information provided by the JVM

Changes in YourKit Java Profiler 8.0.29 from 8.0.28

• Problem solved: no results were shown for some IBM JVMs

Changes in YourKit Java Profiler 8.0.28 from 8.0.27

• IDE integration: IntelliJ IDEA 10 supported

• Problem solved: defective CPU tracing results could be produced on some Linux configurations due to incorrect thread execution times reported by operating system

Changes in YourKit Java Profiler 8.0.23 from 8.0.22

• UI: improved support of low resolution displays: ability to hide "Legend" to give more vertical space for other components
• New startup option "disableoomedumper" disables on OutOfMemoryError snapshots

Changes in YourKit Java Profiler 8.0.22 from 8.0.21

• Problem solved: JRockit: improved handling of incorrect data provided by JRockit JVM under some rare circumstances, which could lead to crashes on memory snapshot capture. JRockit R27.5.6 is affected. It is possible that earlier versions of JRockit are also affected.
• Improvement: JBoss starts with delay=10000 startup option by default, in order to ensure successful startup.

Changes in YourKit Java Profiler 8.0.21 from 8.0.20

• Problem solved: applications using scala might fail starting with the profiler, due to some odd bytecode patterns generated by scala compiler
• Memory profiling: HPROF snapshots: object shallow sizes are calculated more accurately, taking into account some tricky cases of field alignment in memory. Note: if a HPROF snapshot has snapshot index file created with an earlier version of the profiler, remove or re-create the index file.
• Bug fixed: fixed issue which might prevent successful startup of profiled application running on some builds of IBM Java 6 (e.g. WebSphere)
• Non-Windows: improved diagnostic on attempt to start yjp.sh with an outdated Java version

• Memory profiling: extended range of partially-incorrect HPROF snapshots produced by old JVMs which can be successfully opened
• Mac OS X: problem solved: on low memory snapshots could be captured in inappropriate situations
• UI: Threads view: improvement: thread state colors are now configurable. Use legend's popup menu to configure the color.
• JRockit: improved handling of incorrect data provided by JRockit JVM under some rare circumstances, which could lead to crashes on memory snapshot capture and/or to invalid memory snapshots

Changes in YourKit Java Profiler 8.0.18 from 8.0.17

• Mac OS X: fixed possible exceptions in UI which might arise selecting items in comboboxes

Changes in YourKit Java Profiler 8.0.17 from 8.0.16

• Mac OS X: the profiler UI starts with a 64-bit Java if available, which results in better performance and faster UI
• Ability to run the profiler UI with OpenJDK. Anyway, because OpenJDK core UI classes are still buggy, it is strongly recommended to run on Sun Java instead.
• Problem solved: possible error capturing a memory snapshot of WebLogic caused by incorrect behavior of outdated Java version bundled with the server
• Bug fixed: exception on attempt to sort table by some columns after hiding other columns
• Bug fixed: possible false notification about memory snapshot captured in background

Changes in YourKit Java Profiler 8.0.16 from 8.0.15

• Bug fixed: exceptions in UI with multiple snapshots open under certain circumstances (mostly running non-Windows 32-bit profiler UI)
• IDE integration: NetBeans: bug fixed: plugin settings "Advanced | Startup options" might be ignored when profiling web applications

Changes in YourKit Java Profiler 8.0.15 from 8.0.14

• Bug fixed: possible exception on saving index for snapshots bigger than 2 Gb in size

Changes in YourKit Java Profiler 8.0.14 from 8.0.13

• Memory snapshot index improvement: if a memory snapshot file has been replaced with another snapshot with same file name, its index file, if exists, will no longer be valid. Such situations are now detected automatically on snapshot open: the invalid index will be automatically re-created. Note: index files created with older versions of the profiler (8.0.0-8.0.13) will not longer be valid in 8.0.14, and will be re-created on snapshot open. If you explicitly save index files, please ensure that you use the newest version of the profiler.
• Bug fixed: opening a snapshot specified with a relative path from command line ("-open") might cause exceptions in UI
• Bug fixed: "Memory | Strings by Pattern... (Ctrl+F)" action could throw an exception if "Search in byte[] instances using encoding" option was enabled for snapshots with no primitive values
• Bug fixed: incorrect UI elements in the popup hint which suggests to transfer a remote snapshot automatically captured on event

Changes in YourKit Java Profiler 8.0.13 from 8.0.12

• IDE integration: NetBeans: problem solved: start of profiled application might under certain circumstances fail with error: cannot start: unknown option ''
• Minor fixes in UI

Changes in YourKit Java Profiler 8.0.12 from 8.0.11

• Optimization: UI: monitor and exception views are faster
• Problem solved: telemetry might stop updating due to a bug in JVM running with -XX:+DisableExplicitGC

Changes in YourKit Java Profiler 8.0.9 from 8.0.8

• New feature: values of primitive arrays (int[], boolean[] etc.) are shown directly in object explorers
• Optimization: profiler agent does not perform operations that are unnecessary when all byte-code instrumentation is disabled (startup options "disablealloc", "disablecounts", "disablej2ee"). This results in faster class loading.
• Ability to disable exception telemetry to ensure minimum profiling overhead
• Solaris: bug fixed: demo application might fail starting if the profiler UI ran on a 64-bit JVM
