RFR(S): 8132704: [TESTBUG] jdk/internal/jimage/ExecutableTest.java incorrectly asserts all files to be executable

[Volker Simonis]

Hi,

can somebody please review this test fix:

http://cr.openjdk.java.net/~simonis/webrevs/2015/8132704/
https://bugs.openjdk.java.net/browse/JDK-8132704

The initial test checked that all the files in the bin/ directory are
executable by everybody. Unfortunately this was too optimistic because
in the closed build the bin/ directory contains configuration files
which are not executable.

The new version of the test uses a predefined static list of
executables which are checked for the executable permissions if the
corresponding files exist.

Thank you and best regards,
Volker
