/**
|
|
* The test against the method <code>com.sun.jdi.VirtualMachine.redefineClasses()</code>
|
|
* and checks up the following assertion: <br>
|
|
* "If <code>canUnrestrictedlyRedefineClasses()</code> is <code>false</code>,
|
|
* attempting to change a method will throw <code>UnsupportedOperationException</code>
|
|
* exception"<br>
|
|
* On debugee part there is an interface that has three method declarations:<br>
|
|
* <code>abstract public void dummyMethod01();</code> <br>
|
|
* <code> public void dummyMethod02();</code> <br>
|
|
* <code> void dummyMethod03();</code> <br>
|
|
* JLSS 9.4 says "...every method declaration in the body of an interface is
|
|
* implicitly abstract..." and "...every method declaration in the body
|
|
* of an interface is implicitly public..."
|
|
* The test tries to redefine this interface, manipulating modifiers of
|
|
* these methods, and expects UnsupportedOperationException will not be thrown.
|
|
*
|
|
* The test consists of the following files: <br>
|
|
* redefineclasses015.java - debugger <br>
|
|
* redefineclasses015a.java - initial debuggee <br>
|
|
* newclassXX/redefineclasses015a.java - redefining debuggees <br>
|
|
*
|
|
* This test performs the following cases:<br>
|
|
* 1. newclass01 - deleting <code>abstract</code> modifier from
|
|
* <code>abstract public void dummyMethod01()</code> <br>
|
|
* 2. newclass02 - deleting <code>public</code> modifier from
|
|
* <code>abstract public void dummyMethod01()</code> <br>
|
|
* 3. newclass03 - deleting <code>abstract</code>,<code>public</code> modifiers from
|
|
* <code>abstract public void dummyMethod01()</code> <br>
|
|
* 4. newclass04 - deleting <code>public</code> modifier from
|
|
* <code>public void dummyMethod02()</code> <br>
|
|
* 5. newclass05 - adding <code>abstract</code> modifier to
|
|
* <code>public void dummyMethod02()</code> <br>
|
|
* 6. newclass06 - adding <code>abstract</code> modifier to
|
|
* <code>void dummyMethod03()</code> <br>
|
|
* 7. newclass07 - adding <code>public</code> modifier to
|
|
* <code>void dummyMethod03()</code> <br>
|
|
* 8. newclass08 - adding <code>abstract</code>,<code>public</code> modifiers to
|
|
* <code>void dummyMethod03()</code> <br>
|
|
* The test checks two different cases for suspended debugee and not
|
|
* suspended one.
|
|
* When <code>canRedefineClasses()</code> is <code>false</code>, the test is
|
|
* considered as passed and completes it's execution.
