-------------------------------------
Summary: Occasional resource leak in SolrConfig.ResourceProvider
Key: SOLR-16628
URL: https://issues.apache.org/jira/browse/SOLR-16628
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 8.9
Reporter: Michael Gibney
Currently, xml config file parsing can in exceptional circumstances lead to
resource leaks (InputStream not being closed). This has occasionally [shown up
in
tests|https://issues.apache.org/jira/browse/SOLR-16336?focusedCommentId=17678323#comment-17678323]
and presumably could also manifest in the wild.
I suspect (but am not certain) that these changes may have been introduced in
version 8.9 by SOLR-15337 (closing of byte streams in xml parsing is unusual
iiuc in that according to spec, closing is handled internal to the parser, so
it's easy to rely on that behavior and things will usually be ok. But we should
take extra steps to ensure the InputStreams are always closed).
