On FreeBSD latest repository contains OpenJDK 8.192.26 - with this doesn't work the angle creation.

See the discussion here: https://bugs.freebsd.org/bu...


Maybe it's a bug in Geogebra?

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


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.

There is not another program involved.

The angles defining doesn't work in GeoGebra - but only in specific case/environment (OpenJDK provides java).

If you've some time please install FreeBSD (in a VM), install geogebra (pkg install geogebra) and check this strange behavior. I'm not a developer so I can't help about finding the reason of the bug - but if you've an idea what can/should check or try I would help willingly.

We'll check this, but I am afraid that you work with version 4 that is not supported any longer.

We're using GeoGebra 5.0.513.0.

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.
