In which memory is saving Java ClassLoader instance

Question

I want to know where the ClassLoader instance is saving, in which memory. Is it saving in heap or in permgen? And if I have a custom ClassLoader( for example JasperReports loads his own ClassLoader which calls JRClassLoader ), instance of it is also saving in heap memory or in permgen?

Answer 1

Classloader is not an exception from the rules, so:

• ClassLoader instance is created on heap,
• ClassLoader class is like any other class it is created on permgen (till Java 7)
