I still don`t really get the issue since this is only an issue while developing GWT (am I right?)

As far as I know the jars we are packing (gwt-servlet,...) do not depend on a certain JVM. 
Can people who need an IBM JVM running for their servers not simply use the -noserver option with an Oracle JDK?

No, it's an issue when compiling with the GWT Compiler while processing the gwtar files packaged in the gwt-user.jar (see issue 7530).
And the Oracle JDK is apparently not an option on some OSes (see the thread in gwt-steering)
Moreover, the fix seems to be rather simple: follow java.io.Serializable contract and provide an explicit serialVersionUID (and make sure we change it whenever we modify the classes)
