----------------------------
Summary: XML Parser reset() detection no working in weblogic
12.2.1.3
Key: TIKA-3009
URL: https://issues.apache.org/jira/browse/TIKA-3009
Project: Tika
Issue Type: Bug
Components: core
Affects Versions: 1.23, 1.22, 1.21, 1.20
Environment: JDK 1.8.0_231
Oracle Weblogic Server 12.2.1.3
Reporter: Daniel
Starting with tika 1.20 the org.apache.tika.utils.XMLReaderUtils try to detect
if a XML parser supports the reset() functionality by calling reset() during
the poolParser creation and watching for a UnsupportedOperationException.
This unfortunately does not work in weblogic server as the attained
RegistryParser itself caches underlying SAX parsers. Only after first use the
reset() of the underlying SAXParser is called and will produce the
UnsupportedOperationException. A first call to reset() will not produce this
exception and XMLReaderUtils thinks, the parser supports reset() which in
effect is not true.
This results in exhaustion of the parser pool and intermittent errors and
delays in processing as the pool is reset when a parser is not available after
5 minutes.
