A dummy java executable (actually a jar) was required to develop init scripts without access to the client’s application.   The process of creating a Java ‘sleep’ application and wrapping within a ‘jar’ complete with manifest was not obvious to me.  The ‘thread.sleep’ also didn’t work as I expected, requiring an additional exception handler.  Not to mention the requirement for the manifest to require multiple new lines before being syntactically correct (and no report otherwise when incorrectly parsed, except ‘no main manifest attribute’ when attempting to run).  Why Java, WHY?

The following tgz contains both the compiled java executable plus source, manifest and instructions to build / compile the jar should the wait time (default 100 seconds) need to be modified.

The .jar can be executed with:-

java -jar WaitLoop.jar
