Java Reference
In-Depth Information
The graph in the middle tab is useful for detecting "memory leaks" (Java has garbage
collection, therefore in theory memory leaks are impossible. However, if we keep
references to objects that are no longer needed they are never garbage collected,
therefore a memory leak is possible). The purple line in the middle graph indicates
the amount of time the JVM spends doing garbage collection. The red line indicates
Surviving Generations . A generation is a set of objects that were created within two
garbage collection intervals. A surviving generation is a generation that survived
one or more garbage collections. We can force our application to garbage collect by
clicking on the icon in the Profiling control panel:
