Coverity static analysis, Resource leak, LdapsecurityRealm (Elytron) -------------------------------------------------------------------- Key: WFLY-8094 URL: https://issues.jboss.org/browse/WFLY-8094 Project: WildFly Issue Type: Bug Components: Security Reporter: Martin Choma Assignee: Jan Kalina Coverity static analysis found 8 occurence of Closeable object LdapIdentity not closing properly. https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95643... {{LdapIdentity}} in {{close()}} method just close provided dirContext. {{LdapIdentity}} does not create dirContext by itself. So it looks to me it is no necessary to implement Closeable in {{LdapIdentity}}, as code where dirContext was created should be responsible for closing it (and according to coverity it is closed properly everywhere). {code:java|title=LdapSecurityRealm.java} private class LdapIdentity implements Closeable { private final String name; private final DirContext dirContext; private final String distinguishedName; private final SearchResult entry; LdapIdentity(String name, DirContext dirContext, String distinguishedName, SearchResult entry) { this.name = name; this.dirContext = dirContext; this.distinguishedName = distinguishedName; this.entry = entry; } String getName() { return this.name; } DirContext getDirContext() { return this.dirContext; } String getDistinguishedName() { return this.distinguishedName; } SearchResult getEntry() { return this.entry; } @Override public void close() throws IOException { try { dirContext.close(); } catch (NamingException e) { log.debug("LdapSecurityRealm failed to close DirContext", e); } } } {code}
