Classification of ClassCastExceptions doesn't work in JDK 11 (OpenJDK) [SPR-17093]

[spring-projects-issues]

Jens Schauder opened SPR-17093 and commented

SimpleApplicationEventMulticaster.matchesClassCastMessage fails to match cases it should match in JDK 11.

The reason seems to be that instead of starting with the class name or module/class name the message now starts with "class " followed by the class name, which (I think) is the result of the Class.toString() method.

I came across this due to a failing build with Spring Data JDBC examples (https://travis-ci.org/spring-projects/spring-data-examples/jobs/407985295)

So they changed the ClassCastException message twice in a year... and still don't bother exposing the affected Class reference :-(

I've added a starts-with check for the full Class.toString() representation... backporting this to 5.0.9 and 4.3.19 for JDK 11 runtime compatibility there.
