Did you read their migration guide?

It says that despite the backwards incompatibility tag on v3, most upgrades are as simple as updating imports to use lang3 in place of lang.

There are some classes and methods that were removed, which any IDE and compiler will quickly identify for you.

I think the more dangerous areas are where the behavior and contracts of methods has changed. For example, see this note:

StringUtils.isAlpha, isNumeric and isAlphanumeric now all return false when passed an empty String. Previously they returned true.

If your code is using those methods, you may see different behavior. It's gonna be up to you to see if your code uses them and if so, if you care.

r/java on Reddit: Look how they massacred my boy (Apache Commons Lang)
August 21, 2025 -

Seriously, what madness drove the commons lang contributors to deprecate StringUtils.equals()?

I'm gonna rant for a bit here. It's been a long day.

I spend all morning in an incident call, finally get time to do some coding in the afternoon.

I make progress on a bug fix, clean up some dead code like a good boy scout, and I’m feeling like I actually accomplished something today.

Oh, this service is getting flagged for CVE-2025-48924? Let me take care of that.

And then, confusion. Anger.

Deprecated method? StringUtils.equals()? That can't be.

Sure as shit, they deprecated it. Let's see what has been replaced with.

Strings.CS.equals()? Is that character sequence? No, it's case sensitive. Fucking hell. I harp on juniors for their silly acronyms. Did not expect to see them in a library like this. Just unnecessary. If Java developers had a problem with verbosity, well, they wouldn't be Java developers.

I'll admit I've been an open-source leech, contributing nothing to the community, but this one has lit a fire in me.

If this issue isn't resolved, are there any volunteers to help with a fork? I feel like common-sense-lang3 would be an appropriate name for an alternative.

I despise anything that obfuscates the meaning of code from the reader, as too many tenured "geniuses" are actually using bad code to limit the productivity of their coworkers. 'hist' for history/histogram, 'perf' for performance, etc. I used an electronic typewriter once, things are better now and we 'totes' don't need 'abbrevs'. Seems like it would have been better to leave it as Strings.equals() and add a new method for Strings.equalsIgnoreCase() - because the latter would come up in your autocomplete immediately after the former and it would become immediately obvious which method does which.

Try running the following commands and examine the output:

$ mvn dependency:tree
$ mvn help:effective-pom

Look for commons-lang, maybe something will draw your attention like excludes or dependency overrides. Also, is:

$ mvn dependency:copy-dependencies

copying commons-lang JAR to your target?

Adding following dependency to pom.xml in dependencies tag helped me:

    <groupId>org.apache.commons</groupId>
