User Defined Java Expression - regression/deprecation on StringUtils object

[dave-csc]

Hello Hop community,

I set up a UDJE transform with this custom instruction:
org.apache.commons.lang.StringUtils.replaceEach(anno_cf,"LMNPQRSTUV".split(""),"0123456789".split(""))

The objective of this expression is to replace in a string (anno_cf in this example) every character mentioned in the first string with the corresponding character in the second string (hence perform L -> 0, M -> 1, N -> 2 and so on)

Starting from Hop 2.18.1 (or JDK 21?) this expression stopped working, the error returned is
org.codehaus.commons.compiler.CompileException: Line 1, Column 37: Unknown variable or type "org.apache.commons.lang.StringUtils"

It seems that the StringUtils object has been replaced or deprecated, how can I replace it to an equivalent one?

Thanks for answering :)

Lang has been upgraded to lang3 I think this function will still exist so just adding a 3 should do the trick.

I actually found issue #6814 just after posting... but yes, I just needed to replace "lang" with "lang3".

Thanks @hansva anyway... :)
