jexec fails to execute simple helloworld.jar

jdk9 and jdk10 fail to execute a simple hello-world jar with jexec :

jdk9/images/jdk/lib/jexec /java_test/hellojar/helloworld.jar
invalid file (bad magic number): Exec format error

While it works with jdk7 :

jdk7/lib/jexec /java_test/hellojar/helloworld.jar
Hello world from a jar file


It seems change "8156478: 3 Buffer overrun defect groups in jexec.c " which changed jexec.c caused
the issue in jdk9/10.
