I agree with David.

The solution seems excessively complex for a simple issue.

We are indeed already testing for the executable permission, so we check 
the right thing. The error message does not match what we test, however.

Simply changing
AC_MSG_ERROR([Could not find $2 in the Boot JDK])
into
AC_MSG_ERROR([The file $2 in the Boot JDK is missing or not executable])
will match the test we actually do (test -x), and will provide the user 
with enough information to continue solving the problem.

I have a hard time believing it is a common problem that a JDK 
installation exists, where the executable permission is missing. So it's 
reasonable to have this as a last time check, and not as part of the 
already complext BOOTJDK_DO_CHECK logic.
