/**

|
|
* An <code>ExceptionInInitializerError</code> is thrown when an uncaught
|
| 44 |
|
|
* exception has occurred in a static initializer or the initializer for a
|
| 45 |
|
|
* static variable. In general, this wraps only RuntimeExceptions, since the
|
| 46 |
|
|
* compiler does not allow a checked exception to be uncaught in an
|
| 47 |
|
|
* initializer. This exception only occurs during reflection, when a class
|
| 48 |
|
|
* is initialized as part of another action.
