* @summary converted from VM Testbase nsk/jdb/eval/eval001.
* VM Testbase keywords: [jpda, jdb]
* 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.
* COMMENTS

* @library /vmTestbase
