/**
 * The test checks that the JDI method
 * <code>com.sun.jdi.ClassType.newInstance()</code>
 * properly throws <i>IncompatibleThreadStateException</i> - if the
 * specified thread has not been suspended by an event.<p>
 *
 * The test works as follows. Debugger part of the test attempts
 * to construct a new instance of main debuggee class <i>newinstance009t</i>
 * using thread <i>newinstance009tThr</i> being previously suspended
 * by the JDI method <i>ThreadReference.suspend()</i> instead of by
 * an event. The exception is expected to be thrown.
