Intermittent IndexOutOfBoundsException on render

See original GitHub issue

Markwon version: 4.0.2

I’m not really sure how to reproduce the issue, but am seeing occasional crash reports from Crashlytics like this:

Caused by java.lang.IndexOutOfBoundsException: setSpan (4007 ... 4043) ends beyond length 4007
       at android.text.SpannableStringBuilder.checkRange(SpannableStringBuilder.java:1327)
       at android.text.SpannableStringBuilder.setSpan(SpannableStringBuilder.java:688)
       at android.text.SpannableStringBuilder.setSpan(SpannableStringBuilder.java:680)
       at io.noties.markwon.SpannableBuilder.spannableStringBuilder(SpannableBuilder.java:323)
       at io.noties.markwon.MarkwonImpl.render(MarkwonImpl.java:61)
      // ...

I’ve not been able to reproduce the problem, nor does it seem specific to any device/API level/manufacturer. Perhaps some kind of race condition?

Hello @damianw !

You are bringing attention to an important issue actually. Why exactly a (mutable) Visitor is reused for a Markwon instance… It’s kind of legacy and I think there must be no performance-wise downsides if visitor won’t be reused (thus making Markwon thread-safe). I’m going to take a look
