Print suppressed exceptions in JShell

[Chen Liang]

I think it is probably just an oversight. This seems to be printed by JShellTool::displayEvalException, which shouldn't be too hard to add printing for suppressed exceptions.

Subject: Print suppressed exceptions in JShell

Is there any reason why JShell does not print out suppressed
exceptions? I think it would be good to print them.

    jshell> new Throwable()
    $1 ==> java.lang.Throwable

    jshell> new Error()
    $2 ==> java.lang.Error

    jshell> $1.addSuppressed($2)

    jshell> throw $1
    |  Exception java.lang.Throwable
