|
49 * This test verifies the use of the hidden fileManager.deferClose |
|
50 * option, to work around the limitation that javadoc objects |
|
51 * (like RootDoc and related types) should cannot normally be used |
|
52 * after javadoc exits, closing its file manager (if it opened it.) |
|
53 * |
|
54 * The test runs javadoc on a chain of classes, 1 in source form, |
|
55 * and 2 in a jar file. javadoc/javac will "complete" classes found |
|
56 * in source, but will eagerly "classes" in class form. |
|
57 * The chain is p/Test.java -> lib/Lib1.class -> lib/Lib2.class. |
|
58 * After javadoc exits, the classes are examined, to finally force |
|
59 * the classes to be completed, possibly causing javac to try and access |
|
60 * references into a .jar file system which has now been closed. |
|
61 * |
|
62 * The test runs two test cases -- one without the workaround option, |
|
63 * to test the validity of the test case, and one with the workaround |
|
64 * option, to test that it works as expected. |
