| /* @test |
| * @bug 4487532 |
| * @summary When the system property "sun.rmi.server.suppressStackTraces" is |
| * set to boolean true, then the RMI runtime should take positive action to |
| * counteract the new feature in 1.4 of an exception's stack trace being part |
| * of its serialized form so that the server-side stack trace of an exception |
| * that occurs during the execution of a remote method invocation gets |
| * marshalled to the client. In most cases, this feature-- along with the |
| * final fix to 4010355 to make the server-side stack trace data available |
| * at the RMI client application level-- is highly desirable, but this system |
| * property provides an opportunity to suppress the server-side stack trace |
| * data of exceptions thrown by remote methods from being marshalled, perhaps |
| * for reasons of performance or confidentiality requirements. |
