Bug ID: 54702
Summary: File descriptor leak at web.xml loading
Product: Tomcat 7
Version: 7.0.33
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: jeanmarie.lam...@free.fr
Classification: Unclassified
Hello
I think I've found a file descriptor leak in file
/tomcat/trunk/java/org/apache/catalina/startup/ContextConfig.java (method
getGlobalWebXmlSource).
A stream is from file "web.xml" is not closed.
private WebXml getDefaultWebXmlFragment() {
...
1284 InputSource globalWebXml = getGlobalWebXmlSource();
...
1337 // Parse global web.xml if present
1338 if (globalWebXml == null) {
1339 // This is unusual enough to log
1340 log.info(sm.getString("contextConfig.defaultMissing"));
1341 } else {
1342 parseWebXml(globalWebXml, webXmlDefaultFragment,
false);
1343 }
Here is the full stack trace
