First of all our recommendation is to always use latest released version, which is as of today 0.7.9 and not 0.7.4.
Secondly as was described in this mailing list many times: JaCoCo always creates empty dump file at startup to guarantee that location is writable. Then it registers standard JVM Shutdown hook ( see http://docs.oracle.com/javase/7/docs/api/java/lang/Runtime.html#addShutdownHook(java.lang.Thread) ) that will write all collected information, but whose execution not guaranteed if JVM was not gracefully terminated. So the thing to check - is that application under test is terminated gracefully and not just killed. Also be aware that there is JVM bug ( https://bugs.openjdk.java.net/browse/JDK-8154017 ) - when the main thread is in the interrupted state the JVM shutdown hooks are not properly executed. So also please make sure that main thread of application is not left in interrupted state. HTH.
