Do not use JProfiler 5 for anything. It is a very old version. JProfiler 7.1 (the current version can profile Java 1.4 or higher.

Answer 2

Use latest JProfiler version, available here

Please see the installation instructions here .

Answer 3

That is because of problem about memory chunk(See below reference for details). If the program has new version, use newer but sometimes programs dont have new version and you have to use it essentially. If any program(not just JProfiler) gives that problem, do below steps:

1. Search for .vmoptions under the program folder.
2. Open it with text editor.
3. Decrease -Xmx size(try decreasing order, for ex: 512m,256m,128m,64m) until finding right size. For each size try to start the program.
