CVE-2022-21496: Medium severity ibm cognos analytics vulnerability

Inconsistencies were found in the way the java.net.URI and com.sun.jndi.toolkit.url.URI classes in the JNDI component of OpenJDK parsed URI strings. These inconsistencies could be used to make a Java application accept invalid or malformed URI strings.

Parsing of URL strings in built-in JNDI providers were made more strict as part of the fix. For more information, see the following release notes for Oracle JDK 7u341, 8u331, 11.0.15, 17.0.3, 18.0.1:
