dcache-billing-indexer seems to be broken with Java 17 and dCache 10.2

commons.apache.org says:

"Using this constructor prevents IDEs from warning if the underlying input stream is never closed. Use wrap(InputStream) instead."

@VilleS1 I have no idea how it was working in the past. Did you use only uncompressed files?

The workaround until we release the fix:

update /usr/share/dcache/lib/billing.sh as (add commons-io into classpath):

 billing_indexer() # $* = arguments
 {
     CLASSPATH="$(printLimitedClassPath slf4j-api logback-classic logback-core logback-console-config \
-        jul-to-slf4j commons-compress gson spring-core guava dcache-common common-cli cells dcache-core \
+        jul-to-slf4j commons-compress commons-io gson spring-core guava dcache-common common-cli cells dcache-core \
         curator-client)" \

I just started using compressed logs to save disk space and noticed dcache-billing-indexer has problems. Indexing compressed log works with your patch and it also fixes another bug which I did not report. "dcache billing" command was unable to show logs from compressed log files. With your patch it works as it should.
