Adrien Grand updated LUCENE-7956:
---------------------------------
Attachment: LUCENE-7956.patch
Here is a patch
- Recursion has been replaced with a while loop
- It uses CharacterUtils, which is aware of supplementary chars, in order to
fill the buffer. This helps avoid loading more data in memory in the case that
the last char in the buffer is a surrogate.
> ICUNormalizer2CharFilter may fail with a StackOverFlow error

> ICUNormalizer2CharFilter recursively fills up a buffer of 128 chars until the
> last char is neither a surrogate nor inert. On large inputs of non inert
> characters, this can cause a stack overflow error.
