The SecurityClassLoader Class contains the following fields.
codeBase | The codebase URL associated with code from the class loader. |
threadGroup | The loader's thread group. |
This thread group serves as the master thread group for all code associated with this class loader. For applets, each individual applet instance will have a sub-thread group of this thread group. The security system uses this thread group to determine the active context-based thread group at any given point.
For more details on how the security system uses this thread group, see the StandardSecurityManager.getThreadGroup method.
