 * @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

 * @run driver jdk.test.lib.FileInstaller . .
