/**
 * This test checks that the JVMTI function <code>GetLocalVariableTable()</code>
 * returns local variable information properly including variables with generic
 * types.<br>
 * The test creates a dummy instance of tested class <code>localtab005a</code>
 * which must be compiled with debugging info. Then an agent part obtains the
 * local variable table for the following methods of localtab005a:
 * <li>constructor
 * <li>static method statMethod()
 * <li>instance method insMethod()<br>
 * Some local variables of these methods have generic types. The generic
 * signature should be returned properly for these variables, and NULL for
 * non-generic ones.
