RFR(S) 8227435: Perf::attach() should not throw a java.lang.Exception

[Langer, Christoph]

Hi Ralf,

looks good. Prior to pushing you’ll have to take care of the copyright years in the files you touched ��

cc-ing hotspot-runtime, because I think it affects this area, too.

Thanks
Christoph

Please review this small change. It changes the exception which will be thrown when the perf file has not yet the correct size. Instead of throwing the (not declared) java.lang.Exception, we will now throw java.io.IOException, which is expected by the calling code.
