You should have received JProfiler’s support email. Just in case I’m quoting it here:
Thanks for your email. I am no eclipse expert, but I just downloaded the SDK
and I can active the Profile command directly after installation. There is no
profiler there of course, so the toolbar button is disabled.
We register JProfiler like this in our plugin.xml file:
<launchDelegate
delegate=”com.jprofiler.integrations.eclipse.delegates.LocalJavaDelegate”
id=”com.jprofiler.integrations.eclipse.delegates.LocalJavaDelegate”
modes=”profile”
name=”JProfiler”
type=”org.eclipse.jdt.launching.localJavaApplication”>
</launchDelegate>
You can see that the extension point
org.eclipse.jdt.launching.localJavaApplication is from the JDT. With eclipse
3.4, there came a new built-in profiler support that supports more than one
profiler at the same time. Maybe this is what broke the support.
