Description

Internally, the class org.apache.commons.text.lookup.InterpolatorStringLookup normalizes its string lookup map with lower-case keys. The goal probably to make keys cases insensitive so you can say "${env:USER}" or "${ENV:USER}" or "${Env:USER}".

The method org.apache.commons.text.lookup.StringLookupFactory.addDefaultStringLookups(Map<String, StringLookup>) does not convert keys to lower case before adding entries to the string lookup map such that string look ups are not found when resolving variables.

This means that string lookup keys like "resourceBundle" that are mixed case strings are not found and therefore not applied.

The list of keys that are not applied is:

• base64Decoder
• base64Encoder
• resourceBundle
• urlDecoder
• urlEncoder
