| 35 /* | |
| 36 * This test operates in phases to test retrieving the qualified name | |
| 37 * of anonymous classes from type elements modeling the anonymous | |
| 38 * class. The type elements are generated using both source files and | |
| 39 * class files as the basis of constructing the elements. | |
| 40 * | |
| 41 * Source files will be tested by the @compile line which runs | |
| 42 * TestAnonSourceNames as an annotation processor over this file. | |
| 43 * This compile line is expected to fail until 6930507 is fixed. Once | |
| 44 * bug 6930507 is fixed, the "@compile/fail -processor ..." and | |
| 45 * following "@build..." steps can be replaced with a single "@compile | |
| 46 * -processor ..." directive. | |
| 47 * | |
| 48 * Class files are tested by the @run command on this type. This | |
| 49 * class gets the names of classes with different nesting kinds, | |
| 50 * including anonymous classes, and then invokes the compiler with an | |
| 51 * annotation processor having the class files names as inputs. The | |
| 52 * compiler is invoked via the javax.tools mechanism. | |
