String Handling with Apache Commons' StringUtils Class in Java - GeeksforGeeks
April 28, 2025 - All the methods are static, so they can be accessed without creating an object of the StringUtils class. The methods are useful in different scenarios such as checking if a string is empty, reversing a string, or counting the number of occurrences of a substring in a string. Note: You'll need to have the Apache Commons Lang library added to your project's classpath in order for this program to compile and run successfully.

Apache commons lang and lang3
The conservative thing to do is update any <dependency> to commons-lang that has a lower revision bound of 3.x or higher. Afterwards, would people have to wipe out their /.iv2/cache directories to account for changing checksums for ivy.xml files? Is that okay? I don't think that will be necessary. This change will be backward-compatible in the near term so it doesn't matter if people are still caching the old ivy.xml versions. The JAR you end up with will be the same.
