java.lang.IllegalArgumentException: NTFS ADS separator (':') in file name is forbidden.

Hi,
I am running Sonatype Nexus Repository OSS 3.69.0-02 on Windows.
I have set up a proxied Helm repo for the Bitnami helm charts (source https://charts.bitnami.com/bitnami). This was working fine.

Starting from today (18.11.2024), I can’t download the index.yaml from Nexus anymore, I get a file of length 0. In the log I see a message “java.lang.IllegalArgumentException: NTFS ADS separator (‘:’) in file name is forbidden.”

Has anybody else seen this problem? Is there a workaround?

Many thanks
Ulf
