Missing saxon StyleSheet for dcache-info-provider

Dear dCache developers,

We at KIT have made an attempt to install dCache 10.2.10 on our test instance at GridKa running on RHEL 8:

https://www.dcache.org/old/downloads/1.9/repo/10.2/dcache-10.2.10-1.noarch.rpm

We have noticed then, that for running the dcache-info-provider, the following error message is appearing:

> dcache-info-provider
Error: Could not find or load main class com.icl.saxon.StyleSheet
Caused by: java.lang.ClassNotFoundException: com.icl.saxon.StyleSheet

So the saxon java class seems to be missing.

To resolve that, we had to add this class by hand, at first downloading the corresponding .zip file:

> wget https://github.com/Saxonica/Saxon-Archive/raw/refs/heads/main/Saxon-6/6.5.5/saxon6-5-5.zip

Then we have extracted the .jar file from it, and moved it to /usr/share/dcache/classes/saxon directory used by dcache-infor-provider.

After that, the tool was working again:

> dcache-info-provider
#  
#  LDIF generated by Xylophone v0.2

#  XSLT processing using SAXON 6.5.5 from Michael Kay 1 (http://saxon.sf.net/)

# 
(...)

We would kindly ask you to re-add this class to the ones needed by dCache, or to make a suggestion to resolve this issue in a different way.

Thank you very much in advance!

Best regards,
