| /* |
| * This test verifies the use of the hidden fileManager.deferClose |
| * option, to work around the limitation that javadoc objects |
| * (like RootDoc and related types) should cannot normally be used |
| * after javadoc exits, closing its file manager (if it opened it.) |
| * |
| * The test runs javadoc on a chain of classes, 1 in source form, |
| * and 2 in a jar file. javadoc/javac will "complete" classes found |
| * in source, but will eagerly "classes" in class form. |
| * The chain is p/Test.java -> lib/Lib1.class -> lib/Lib2.class. |
| * After javadoc exits, the classes are examined, to finally force |
| * the classes to be completed, possibly causing javac to try and access |
| * references into a .jar file system which has now been closed. |
| * |
| * The test runs two test cases -- one without the workaround option, |
| * to test the validity of the test case, and one with the workaround |
| * option, to test that it works as expected. |
