was (Author: llech):
Maven 3.8.4 and the problem is persistent. 

Honestly, wouldn't validating the content of resolver*.properties files before writing them solve the problem? It doesn't look like 2 threads are writing to the same file, because the content is a 'valid' .properties file, only with 'invalid' characters...
