Commercial Java analyzers have an advantage over free ones The one in NetBeans?

Occasionally, I have to do some analysis of Java code. What I want to know is why my boss will investigate in business analyzer instead of just one of Netbeans or JConsole.

What is the killer's function that will help investment?

Solution

I have experience using NetBeans analyzer and Jprobe For performance analysis, I find NetBeans very useful, but Jprobe's advantage is memory analysis

Jprobe has excellent tools for comparing heap snapshots and finding the root cause of memory leaks For example, in Jprobe, you can visually view the heap shapshots graphically, select the node to investigate, and then delete the reference to see whether the instance can be garbage collected
