Class EvalException

java.lang.Object

java.lang.Throwable

java.lang.Exception

jdk.jshell.JShellException

jdk.jshell.EvalException

All Implemented Interfaces:

Serializable

public class EvalException
extends JShellException

Wraps an throwable thrown in the executing client. An instance of EvalException can be returned in the SnippetEvent.exception() query. The name of the throwable thrown is available from getExceptionClassName(). Message and stack can be queried by methods on Exception.

Note that in stack trace frames representing JShell Snippets, StackTraceElement.getFileName() will return "#" followed by the Snippet id and for snippets without a method name (for example an expression) StackTraceElement.getMethodName() will be the empty string.
