After upgrading to Java 8 Update 181, the domain field is now null in the Enterprise Management GUI. Any login attempt results in an instant timeout error.
The issue is occurring because Java 8 Update 181 enables Endpoint Identification for LDAPS connections. In the release notes, Oracle says it could cause applications using LDAPS to no longer be able to connect.
