NamingException and MalformedURLException Errors While Parsing Strings After Updating JDK

Issue

Following a recent update of our OpenJDK (from java-1.8.0-openjdk-1:1.8.0.322.b06-2.el8_5.x86_64 to java-1.8.0-openjdk-1.8.0.332.b09-1.el8_5 .x86_64), we are facing an LDAP connection error causing the following stacktrace :

javax.naming.NamingException: Cannot parse url: ldap://ldap_test.alias:27613 [Root exception is java.net.MalformedURLException: unsupported authority: ldap_test.alias:27613]

We encountered the exact same error case for a completely different application running in an OpenJDK 11 JVM that has also recently been updated (from java-11-openjdk-1:11.0.14.1.1-2.el8_5.x86_64 to java-11-openjdk-1:11.0.15.0.9-2.el8_5.x86_64), with a similar stacktrace:
