 * VM Testbase readme:
 * DECSRIPTION
 * A positive test for the 'eval <expr>' command.
 * The test checks if jdb correctly prints values for the following
 * expressions:
 *  - static field,
 *  - instance field,
 *  - element of array field,
 *  - return value of a method,
 *  - arithmetic expression of local variables,
 *  - return value of public method of the java.lang.String class.
 * The test passes when all printed values are equal to expected ones.
 * The test consists of two program:
 *   eval001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   eval001a.java - the debugged application.
