I just realised that I missed an important bit from the test case in my earlier mail.
The jar file used for the test needs to contain, in addition to the class files, a text file called META-INF/services/java.sql.Driver containing the text
since it is the interaction between the driver being loaded manually and through the Service Provider mechanism which causes the dysfunction.

Note that the repro given in my mail is a bit simpler than the current defect description, especially if you don't have access to the "MyFace" JDBC driver.

We filed a bug report but it got an incident ID JI-9019539 and then disappeared into a black hole.
There does appear to be an issue with those changes. I've located the
incident and moved it to the JDK project as JDK-8076639 .
