JProfiler releases

JProfiler Release 14.0.5

Mon, 04 Nov 2024 08:00:44 GMT

New features:

Support for MongoDB 5.2
Support for Spring WebFlux client 6.1.14+
Support for ktor 3
Prevent native agent warning for Java 24+

Bug fixes:

Regression in JProfiler 14.0.3: Remote attach to a Docker container with a user switch via sudo did not work anymore
Fixed remote attach to Docker containers with a different architecture for certain situations

JProfiler Release 14.0.4

Fri, 06 Sep 2024 07:00:44 GMT

New features:

Full support for profiling Java 23. This update is required if you profile virtual threads or perform async sampling.
Added support for Hibernate 6.6

Bug fixes:

Virtual thread profiling was broken on recent OpenJ9 JVMs

JProfiler Release 14.0.3

Wed, 22 May 2024 07:00:44 GMT

New features:

Security change: If the "address" option is not specified for the -agentpath parameter, the JProfiler agent will only listen on the loopback interface
Security change: By default, the command line utility jpenable will now prepare a JVM for profiling in such a way that only local connections are allowed. jpenable has a new -a option to specify a listening address instead.
Security change: Integration wizards will no longer suggest to configure unencrypted direct TCP connections to remote machines but use SSH connections by default
Security change: The default connection type of a new profiling session is now "Local TCP connection". The old remote TCP connection is discouraged but is still available with the "Unsecured TCP connection" connection type.
Improved the ability to open truncated HPROF files

Bug fixes:

Connecting to a Docker or Kubernetes container did not work if the home directory was mounted with the "noexec" option
When connecting to Kubernetes containers, JProfiler used to query containers in all namespaces, which could take a very long time. Now, only namespaces that are opened in the tree are queried.

New features:

Full support for Java 22 virtual threads
Support for virtual threads in HPROF snapshots

For snapshots, adding a probe telemetry in the telemetry section showed a message to record data under some circumstances

Added a garbage collector probe
Added a JFR event browser when opening JFR snapshots
Opening very large JFR snapshots is now much faster
JFR snapshots also show the GC probe
Added support for JFR recording, also on remote machines, local or remote Docker container or on Kubernetes
Added a gRPC probe and a gRPC remote request tracking type
Near-zero overhead for full sampling when profiling Java 17+
Probe events view: The type filter drop-down now allows the selection of multiple types
Probe events view: When multiple events are selected, the cumulated call tree, CPU hot spots or probe hot spots are shown below the events table
Probe events and control objects views: Scales for duration and throughput columns are now configurable in the view settings dialog.
Probe events, control objects, current monitors and monitor history views: Multi-column filters with range editors for numeric values
Probe events view: Histograms for event durations and recorded throughputs are shown at the bottom. Events can be filtered by selecting an interval in the histograms.
Probe telemetries view: After selecting a time interval with the mouse, the events view will be shown with a corresponding time filter. This also works for probe telemetries that have been added to the VM telemetries.
Probe call tree and hot spots view: Added a "Show events" action that will set a corresponding call stack or hot spots filter and show the probe events view
The "Show events" action and the "Show in heap walker" actions in the control objects views of probes now support multiple selection of control objects
In the telemetry overviews for VM telemetries and probe telemetries, the telemetries can be reordered via drag and drop
VM telemetries that are based on recorded objects are now always shown, with actions to start recording and to show the recorded object views
Selected probe telemetries can be added to the VM telemetry section with actions to start recording and to show the corresponding probe view
Telemetries can be exported as SVG, the PNG export is still optionally available
Current monitor data is now a snapshot rather than continuously updated. A corresponding trigger action and a controller API method are available.
Current monitors and locking graph views now show java.util.concurrent locks
Current monitors and locking graph views now group similar threads. This makes it easier to interpret locking situations with many threads and is important for supporting virtual threads.
Current monitors and locking graph are now also available in attach mode, for java.util.concurrent locks only
Thread history and probe time line views: Threads can be reordered via drag and drop
Thread history and probe time line views: Threads can be sorted by start time or alphabetically
Flame graphs can be exported as SVG
The tooltip in flame graphs is now pinnable, so hovering over the tree can be free of any obstructions from the tool tip
Flame graph colorizations are now persisted
"Show Source" and "Show Bytecode" context menu actions have been added to the flame graph
In the attach dialog reduced the number of "unknown" processes, showing the Java home directory instead
