/** |
|
* Thrown to indicate that the requested class has |
|
* not yet been loaded through the appropriate class loader. |
|
* <p> |
|
* Due to the lazy class linking performed by many VMs, it is |
|
* possible for a field or variable to be visible in a program |
|
* before the associated class is loaded. Until the class is loaded |
|
* all that is available is a signature string. If an attempt is made to |
|
* set the value of such a field or variable from JDI, the appropriate |
|
* type checking cannot be done because the destination class has not been |
|
* loaded. The same is true for the element class of array elements. |
|
* <p> |
|
* It is not advisable to solve this problem by attempting a class load on |
|
* the fly in this case. There are two problems in having the debugger load |
|
* a class instead of waiting for it to load over the normal course |
|
* of events. |
|
* <ul> |
|
* <li>There can be no guarantee that running the appropriate class |
|
* loader won't cause a deadlock in loading the |
|
* class. Class loaders can consist of arbitrary |
|
* Java<sup><font size=-2>TM</font></sup> programming language code and the |
|
* class loading methods are usually synchronized. Most of the work |
|
* done by a debugger happens when threads are suspended. If another |
|
* application thread is suspended within the same class loader, |
|
* a deadlock is very possible. |
|
* <li>Changing the order in which classes are normally loaded may either mask |
|
* or reveal bugs in the application. An unintrusive debugger should strive |
|
* to leave unchanged the behavior of the application being debugged. |
|
* </ul> |
|
* To avoid these potential problems, this exception is thrown. |
|
* <p> |
|
* Note that this exception will be thrown until the class in question |
|
* is visible to the class loader of enclosing class. (That is, the |
|
* class loader of the enclosing class must be an <i>initiating</i> class |
|
* loader for the class in question.) |
|
* See |
|
* <cite>The Java™ Virtual Machine Specification</cite> |
|
* for more details. |
