IndexOutOfBoundsException in RichText demo

[clartaq]

When changing the font of the entire contents of the demo editor pane, an IndexOutOfBounds exception is thrown in the "JavaFX Application Thread".

Steps to reproduce:

1. Start the RichText demo (from the pre-built jar or building in Gradle).
2. Paste the README.md file into the demo.
3. Select All (Ctrl-A)
4. Select a different [font size or font family from their respective ComboBox] (edited by Jordan)

Environment:

• Windows 10 Pro, 64-bit
• RichTextFX 0.6.10

java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

@clartaq Does this also occur using the 0.7-M3 release?

[clartaq]

The same error occurs when using 0.7-M3, whether I paste the contents of the 0.6.10 README.md or the 0.7-M3 version.

Also, using the new command in the demo to read a file produces an OutOfMemoryError when trying to load either of these files.

[JordanMartinez]

I can't reproduce the bug on my end in either of those versions.

Linux Mint 18.1
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Also, using the new command in the demo to read a file produces an OutOfMemoryError when trying to load either of these files.

Could you create a new issue specifically for that and with more details as to the issue? I'm not sure which command to which you're referring.

[JordanMartinez]

Can someone else test this on a Windows environment?

I can confirm that bug, Windows 10 Enterprise, RichTextFX demo 0.6.10

Originally, I ran my test through my IDE which AFAIK delegates to Gradle, and never had the issue arise. The issue does appear on my end when I test it via a terminal.

[clartaq]

Ah, I never tried it through an IDE, just terminals.

[JordanMartinez]

I think this just proves once again that tests (and demos when debugging them) should be run via terminal, not IDE. I'm sure the error occurs even when run via the IDE; the resulting window just probably didn't display it.

Note: this issue also arises when familyCombo, the other comboBox, is used to select a different font family.
