---------------------------------------
Summary: Avoid throwing StackOverflowError when creating RegExp
Key: LUCENE-10474
URL: https://issues.apache.org/jira/browse/LUCENE-10474
Project: Lucene - Core
Issue Type: Improvement
Components: core/other
Reporter: Yannick Welsch
Creating a regular expression using Lucene's RegExp class can easily result in
a StackOverflowError being thrown, for example when the input is larger than
the maximum stack depth. Throwing a StackOverflowError isn't something a user
would expect, and it isn't documented either. StackOverflowError is a
user-unfriendly exception as it does not convey any intent that the user has
done something wrong, but suggests a bug in the implementation.
I would like Lucene to follow the [approach taken by the
JDK|https://github.com/openjdk/jdk/blob/cab4ff64541393a974ea91e35167668ef0036804/src/java.base/share/classes/java/util/regex/Pattern.java#L1441]
and throw an IllegalArgumentException instead to clearly mark this as an input
that the implementation can't handle.
