When trying to instrument a locally via the Atlassian SDK started Confluence with the Java VisualVM for profiling, the following exception is thrown:
Found in Confluence Log / Console
Caused by: java.lang.NoClassDefFoundError: org/netbeans/lib/profiler/server/ProfilerRuntimeCPUFullInstr
What seems to tell that a required class is not provided is actually a complaint that the OSGi subsystem has not been configured properly.
Add the following lines to specify a profile with additional system properties to your Maven POM to configure Confluence:
POM File
<profile>
<id>profiling</id>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-confluence-plugin</artifactId>
<version>6.3.21</version>
<extensions>true</extensions>
<configuration>
<systemPropertyVariables>
<atlassian.org.osgi.framework.bootdelegation>org.netbeans.lib.profiler.*,sun.*,com.sun.*</atlassian.org.osgi.framework.bootdelegation>
<atlassian.org.osgi.framework.system.packages>org.netbeans.lib.profiler.server</atlassian.org.osgi.framework.system.packages>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
</profile>
Start the Confluence server locally using the Atlassian SDK:
Found in Confluence Log / Console
atlas-debug -Pprofiling
Then add a configuration to limit instrumentation to classes you want to take execution performance measurements and start the instrumentation.
