RFR: 8220555: JFR tool shows incorrect message when it cannot access the file

[Yasumasa Suenaga]

Hi all,

Please review this change:

  JBS: https://bugs.openjdk.java.net/browse/JDK-8220555
  webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8220555/webrev.00/

JFR tool shows error message as "could not find file" when it receives
FileNotFoundException from ctor of RandomAccessFile.
According to Javadoc of RandomAccessFile [1], FileNotFoundException
will be thrown when we do not be granted to access the file.
Therefore, the error message misleads the user.

All tests on submit repo seems to be succeeded
(mach5-one-ysuenaga-JDK-8220555-20190313-0612-1175783).
Also it passed :jdk_jfr jtreg tests on my Linux box.


Thanks,

Yasumasa
