Since JDK-8059038 has been backported to JDK 8u, the j2re-image, has the following in folder 'bin':

$ ls bin/
clhsdb hsdb java jjs keytool orbd pack200 policytool rmid rmiregistry servertool tnameserv unpack200

This is wrong, clhsdb and hsdb shouldn't be there for JRE as they don't work anyway:

$ ./bin/clhsdb
Error: Could not find or load main class sun.jvm.hotspot.CLHSDB
$ ./bin/hsdb
Error: Could not find or load main class sun.jvm.hotspot.HSDB

They rely on sa-jdi.jar, which isn't built for j2re-image. These launchers need to be filtered for the JRE case.
