I'm trying to launch jmc, but only 3 dots in UI are displayed. The window can't be resized. I launched the program with logs ./jmc -debug -consoleLog

So no errors in the logs, but there is no possibility to work with UI. How it can be resolved?
The JMC released with most JDK8 update releases is JMC 5.5.0, a fairly old release build on Eclipse 4.4.0 which has some bugs on macOS that could be causing this. It's possible that an older release of JDK8 (<151) will work fine, but I would personally recommend either using JMC 6.0.0 which was released with JDK 9 or JMC 7.0.0, which is the open source version.
EDIT: I just saw that this question duplicates this one and there seems to be a workaround.
