Stack overflow with certain XML files in XMLEditor demo

[dawon]

Hello,

i am working on XML editor with syntax highlighting using RichTextFX. Everything was running smoothly until I started using large XML files. Then my applicatioon and even XML Editor demo started crashing on StackOverFlow exception:

Executing xxx.jar using platform C:\Program Files\Java\jdk1.8.0_51\jre/bin/java
Exception in thread "JavaFX Application Thread" java.lang.StackOverflowError

(etc...)

What is weird: program is working for 15 MB of XML data and it crashes for 2 MB of XML data. I did not spotted any bigger differences in file's structure.

It is working for this data: http://dawon.cz/test1.xml and not working for this: http://dawon.cz/test2.xml

Can you please look into this issue?

Thank you very much

Jakub

I suspect this is related to the regex expressions for parsing. I can run it through the debugger later on after work to try and find the fault.

[dawon]

Well when I debugged it, it seemed to crash after all regexps were done. But I can be wrong...

[cemartins]

Can you get a StackTrace that includes some instruction before the loop?

[dawon]

Unfortunately no. It continues this way all the way down.

This looks like a bug in ReactFX that I resolved months ago, but somehow I never made a release with that fix. I will fix it soon.

[cemartins]

Cool.

[dawon]

Well I am using RichTextFX "fat" jar, so it is possible, that the new release is not in that jar...

[TomasMikula]

I never even released ReactFX with that fix, so it can't possibly be fixed
in RichTextFX.

Please try the new version 0.6.6 and confirm that it is resolved. Thanks.

It works well now, thank you very much for such a fast resolution and keep up the good work!
