classloaders

You analyse further by selecting one of the classloaders in the report to open a new classloader-specific component report.

Even when a classloader is eligible for collection, the runtime only collects classloaders as part of a GC cycle.

Classes and classloaders can still be garbage collected in just as they are in the non-shared case.

Doing lots of reflection can cause many accessor classes and classloaders to be created.

Classloaders are important from the perspective of sharing or isolation between various classes loaded inside the application server JVM.

In this article we will take a look at how servers and frameworks use dynamic classloaders to speed up the development cycle.

Otherwise, the classloaders may not load the appropriate version either for the runtime or for the application.

Often it is not possible to remove all references to instances, classes or classloaders completely from the JVM.

Hotswap is also ignorant of classloaders, it identifies classes only by their name and works only for existing classes.

There are many circumstances where multiple application classloaders are used by Java programs.

It really is a matter of classloaders clashing.

If you use custom classloaders, another issue is that JVMs can decide to unload classes that have become garbage.

As we discussed in Part 1, classloaders use a tree-structured hierarchy.

To make use of dynamic classloaders we must first create them.

It is even possible that the database engine classes will be spread between multiple classloaders.
