Hi, Enhanced exception messages are designed to hide sensitive information such as hostnames, IP addresses from exception message strings, unless the enhanced mode for the specific category has been explicitly enabled. Enhanced exceptions were first introduced in 8204233 in JDK 11 and updated in 8207846.
This PR aims to increase the coverage of enhanced exception messages in the networking code. A limited number of exceptions are already hidden (restricted) by default. The new categories and exceptions in this PR will be restricted on an opt-in basis, ie. the default mode will be enhanced (while preserving the existing behavior). The mechanism is controlled by the security/system property "jdk.includeInExceptions" which takes as value a comma separated list of category names, which identify groups of exceptions where the exception message may be enhanced. Any category not listed is "restricted" which means that potentially sensitive information (such as hostnames, IP addresses, user identities) are excluded from the message text. The changes to the java.security conf file describe the exact changes in terms of the categories now supported and any changes in behavior.
