|
* @bug 4689395
|
|
* @summary converted from VM Testbase nsk/jdb/regression/b4689395.

|
* DESCRIPTION
|
|
* Regression test for the bug
|
|
* 4689395 (P4/S3) "step over" after a class is redefined acts like "step out"
|
|
* Release summary: 1.4
|
|
* Hardware version: generic
|
|
* O/S version (unbundled products): 5.8
|
|
* The test consists of two java-files:
|
|
* b4689395.java - launches jdb and debuggee, writes commands to jdb,
|
|
* reads the jdb output;
|
|
* b4689395a.java - the debugged application.
|
|
* The debugged application (b4689395a.java) defines method minor() that
|
|
* prints four lines into System.out. b4689395 sets a breakpoint on the 54th
|
|
* line
|
|
* System.out.println("A breakpoint is here.");
|
|
* and then redefines b4689395a with newclass/b4689395a. Those classes differ
|
|
* just in the 30th line (period is omitted in newclass/b4689395a). After that
|
|
* the debuggee invokes 'next' command. The test fails if
|
|
* b4689395.ERROR_MESSAGE message appears in output, otherwise the test passes.
|
|
* COMMENTS
|
|
* The test reproduces the bug on Solsparc.
