Install4j8 handling of empty search Sequence changed

We have to make sure our product launches with the java we included in the install4j Setup. In install4j 7 we did this by clearing the JRE Search Sequence and it worked. But with install4j 8 it seems to delete empty search sequence blocks out of the .install4j file when you save it and use the default JRE Search Sequence of JRE_HOME and JDK_HOME. If you open an .install4j File with an empty search sequence block in Install4j 8 it is shown in the UI as empty but after a save with Install4j 8 and reopen the default is shown. We found a workaround by putting only the directory of our included JRE in the JRE Search Sequence. It seems like a bug because in Install4j Java minimum version seems not functional the soulution we used for Install4j 7 was given.
