Lucene: Wildcard not matching number after dot

I recently upgraded from Lucene 3 to Lucene 6, and in v6 I found out that the wildcard ? doesn't match numbers following dots anymore. Here's an example:
string to match: a.1a
query: a.?a
In this example, the query matches the string in Lucene 3, but not in Lucene 6. On the other hand, the query a* matches in both Lucene 3 and 6. Further testing indicates that this difference in behavior only occurs when a dot is followed by a number. I'm using the StandardAnalyzer in both Lucene 3 and 6, by the way.
Does anybody know what's going on here? How can I restore the behavior of Lucene 3, or alternatively, adapt my Lucene 6 query so that it's equivalent to the Lucene 3 ones?
