JProfiler Release 7.1

Thu, 26 Jan 2012 09:00:00 +0100

New features:

JPA/Hibernate probe with support for Hibernate 3.x, Hibernate 4.x, EclipseLink 2.3+ and OpenJPA 2.1+
Probe tracker for tracking selected hot spots or control objects over time
Context menu in views with a call tree view now has an "Add Filter From Selection" action that offers a number of actions to modify the current filters based on the current selection
Ignored methods tab of the filter settings: It is now possible to select all methods of a selected class
Added trigger actions for starting and stopping probe recording
Groovy call site methods are now ignored by default
"Servlet" probe: Added a check box in the servlet probe config for switching off URL splitting in the call tree
Bundled plugin for IntelliJ IDEA 11

Bugs fixed:

JDBC probe: Batch execution parameters in the probe event view showed the data of the last addBatch call for all rows
JDBC probe: Always show physical connections. This eliminates a potentially large number of connection wrappers that are often unused.
Servlet probe: URLs from filter chains were not recorded
Entries in the hot spots view could be shown as "null" after using view filters or restarting recording
When using JRE 7 for the JProfiler GUI, an exception could be thrown when calculating allocation hot spot comparisons
Probe control objects view: Expanded tables with nested properties were not preserved correctly when new control objects were added to the view
Call tree view: exported XML files could be corrupted
Profiling settings: On the "Probes & JEE" tab, the ""Record exact payload call stacks in sampling mode" could not be changed
Probe events and control objects views: Event filter was not persistent when the probe view was changed

JProfiler Release 7.0.1

Thu, 13 Oct 2011 09:00:00 +0200

New features:

Support for profiling on Linux ARM
The JProfiler GUI can now run with a Java 7 JRE (Note: profiling Java 7 has been supported for a long time)
Added "Freeze view" actions for "All objects" and "Recorded objects" views

Bugs fixed:

Changing request tracking types in the startup dialog did not save the session, so the changes were not persistent sometimes
When moving back in the heap walker history, some controls in the references views were disabled (regression in 7.0)
"Go to start" action in the heap walker did not hide the group table at the top if the current object set was created by an inspection
Code completion in script editor: No parameters names were shown for JProfiler API classes
When using the "Add method trigger" action in the call tree to create a trigger with script actions, the scripts were not compiled immediately, so those script actions would have no effect until the next restart
Using the "Set root" action in the call tree multiple times did not work for snapshots
The HTML export of the CPU hot spot view could have empty backtraces under some circumstances
Profiling on Windows 2000 was broken
Object comparison: Creating an allocation tree or an allocation hotspot comparison from the selection was broken
Fixed a rare UTFDataFormatException
