This error is common if using OpenJDK/JRE. Us the Oracle JRE and the issue goes away.

You can use the `alternatives --config java` command and select the Oracle Java as the default.

I have Oracle JDK 1.8.0.162-r1 so that cannot be the issue.

I am on (K)ubuntu 17.10 and using

openjdk version '1.8.0_151'

OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.10.2-b12)OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

I have been using 4.25 successfully daily (with previously created projects) and just created a project now without issues.

I'm guessing some other dependency???

Only update the software as `root`...otherwise some things are not written to their place even if you have premission on the folders.

I had the same issue, I just reinstalled the latest version using `root` then used the program with my own user account and it worked again!
