Here's the code that causes it:
CodeArea c = new CodeArea();

Well... what is going on... o..o

Should it be suspendWhile()??

[TomasMikula]

Hi, the snapshot version that you have on your classpath (richtextfx-1.0.0-SNAPSHOT) uses reactfx-2.0-SNAPSHOT. But on your classpath, you have reactfx-2.0-M4u1. The suspendWhen has only been added recently and is not present in that version of ReactFX.

[euwbah]

I see. Is it necessary to use the snapshot versions for all the required libraries, or would reactfx just do fine? (Also, if I were to use snapshots for all the libraries, would there be severe bugs?).

[euwbah]

Anyways, it's all working properly now :) Thanks!

Is it necessary to use the snapshot versions for all the required libraries, or would reactfx just do fine?

The Snapshot versions are for ReactFX and Flowless. ReactFX needs the snapshot so that #189 gets fixed, among other things. Flowless needed the snapshot so that #213 was possible, among other things. Fortunately, they don't have any bugs that we know of.

Tomas needs to make a new release for both of them, but it seems he has decided to wait until we finish any other updates or new features for RichTextFX that would then invalidate such releases. So, when everything is good to go for 0.7.0, Tomas will probably release new releases for those two libraries, then update the build.gradle file here to use those new releases, and then release 0.7.0.

Ahh I see!
