30 * VM Testbase readme: |
|
31 * DECSRIPTION |
|
32 * A positive test case for the 'untrace methods <thread id>' command. |
|
33 * The debuggee program (untrace001a.java) creates an additional |
|
34 * thread with name like "MyThread-1" and starts it. The jdb |
|
35 * suspends the debuggee at a moment when the additional thread is |
|
36 * waiting for notification for lock objects and then turns on method |
|
37 * tracing for this thread by 'trace methods <thread id>' command. |
|
38 * After expected notification the additional thread invokes checked |
|
39 * debuggee's methods. Thus jdb output must have the trace messages of checked methods' |
|
40 * entrance and exit. |
|
41 * At second phase jdb suspends the debuggee and turns off tracing |
|
42 * by checked command. After resuming the debuggee's additional |
|
43 * thread invokes checked methods again. Tracing messages and debuggee's |
|
44 * suspentions are not expected at this moment. |
|
45 * The test passes if jdb output has one 'enter' messages and one 'exit' |
|
46 * messages for every checked method. |
|
47 * The test consists of two program: |
|
48 * untrace001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output, |
|
49 * untrace001a.java - the debugged application. |
|
50 * COMMENTS |
|
51 * Modified due to fix of the bug: |
|
52 * 4785781 TTY: debuggee hangs in jdb 'untrace001' test in Mantis |
