| * VM Testbase readme: |
| * DESCRIPTION |
| * This test checks that the JDI method: |
| * com.sun.jdi.StackFrame.setValue() |
| * properly throws InvalidTypeException - if the value's type |
| * does not match type of specified variable. |
| * Debugger part of the test tries to provoke the exception by setting |
| * values of different primitive types and own "DummyType" which |
| * are not assignment compatible with the variable type, and not |
| * convertible without loss of information as well. |
