per Doc ID: 225324.996
adding -nojit to edited netasst fixed this problem for me on 8.1.7.4 on rh7.1. Your milege will vary like a Saudi Utility Vehicle (SUV).
$./jre -?
(SUV)va(tm) Runtime Loader Version 1.1.8

In order to understand JITs (Just-In-Time compilers), you must first understand how the Java Virtual Machine (JVM) works. When you write a Java? application, such as the following "hello world" program:
class hello { public static void main(String argv[]) { System.out.println("Hello!"); } }
You first run "javac", the Java Compiler, which turns the Java code into what is known as "bytecodes" and puts them into the "hello.class" file. This class file can then be interpreted on any machine which has a Java Virtual Machine on it. The key word here is "interpreted". The Java Virtual Machine processes each of the bytecodes in the .class file and executes them. This is similar to what other interpreted languages do, such as Basic, LISP, and Smalltalk.
When a JIT is present, the Java Virtual Machine does something different. After reading in the .class file for interpretation, it hands the .class file to the JIT. The JIT will take the bytecodes and compile them into native code for the machine that you are running on. It can actually be faster to grab the bytecodes, compile them, and run the resulting executable than it is to just interpret them. The JIT is an integral part of the Java Virtual Machine, so you never notice it's there, except your Java runs faster. Some environments allow you to choose whether or not to JIT code.
