Commons Lang 3 StringUtils Exception

[Bruzzlee]

Current Windows installer version OmegaT 6.0.1 (with 64-bit JRE) comes with commons-lang-2.6.jar.
But the plugin throws the following message when trying to pack a project:
java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils

Workaround:
Download commons-lang3-3.11-bin.zip from
https://archive.apache.org/dist/commons/lang/binaries/

Extract commons-lang3-3.11.jar
to C:\Program Files\OmegaT\plugins
