Java test program

In openjdk8 (v8.192.26) the Math.asin() method returns wrong values. This can
be reproduced by the attached test program (CheckMathIssue.java). Previous
versions (e.g. 8.172) did return correct results. The comments in the test
program show results of the test program for four different platforms:
- FreeBSD 11.2 openjdk8-8.192
- FreeBSD 11.2 openjdk8-8.172
- MacOs 10.14 Oracle JDK 8.192
- Linux OSMC (ARM) 4.14 openjdk8-8.191

The latter three return identical (and correct) results. So, there seems to be
a bug in  the current version of openjdk8.
