Bad angle creation

Have you got a ggb file or link wit a wrong angle calculation? To react in this forum on another forum, but without a file is rather abstract. So why not discuss it directly here, where you have a direct link to the developers. More, the angle mentioned in the discussion Angle ACB is not at all the result of the command Angle(A, C, B) or the equivalent tool in GeoGebra. The angle is drawn and calculated correctly. So despite the mocking reaction in the forum, the author had better controled hiself first.

The tests (https://bugs.freebsd.org/bu...) shows that

• with OpenJDK 8.181.13 the result is good, the angle is 45
• with OpenJDK 8.192.26 the result is bad (see the picture: https://people.freebsd.org/...)

And if I open your angle.ggb file with "good" OpenJDK the angle is right. But when I open with "bad" OpenJDK the angle is similar as the picture above.

I don't know it's a FreeBSD-specific or OpenJDK-specific problem or maybe a tricky bug in GeoGebra.

In all GeoGebra versions and on the online platform of GeoGebra defining angles works fine and correct.So if you definitely want to open files in another program than GeoGebra and there's something wrong... where would you search for a problem???If you want to use GeoGebra without installing GeoGebra, just use the webversion instead.

How can I remove "Answered" status? It's not answered (solved) yet.

It works fine with 5.0.518.0-d Java 1.8.0_191-1-ojdkbuild-64bit on Windows 10 so it seems very likely that it's a problem with the specific build of OpenJDK 8.192.26 that you are using

I can reproduce the problem in FreeBSD 12.0, but I also agree that the bug must be in the specific build of OpenJDK.
