skip tests that fail with java > 1.8 if java > 1.8 is used

we compare here just that the first part of the version is 1
which is true only for version 1.8, other versions have first number
like 11, 17, 21 and those fail the condition hence the remaining tests
are skipped
we cannot use System.version() here as this is available only since java 9
