RFR: 8334899: Test runtime/cds/appcds/javaldr/ExceptionDuringDumpAtObjectsInitPhase.java failed after JDK-8306580

[Matias Saavedra Silva]

JDK-8306580 changed the text of an error message to better fit the changes introduced by the patch. The test `ExceptionDuringDumpAtObjectsInitPhase.java` expects the old message and thus fails after the change. This patch alters the expected output what is now being generated.
