I use R-OSGi over ECF to call remote services.
After EXACTLY 16 remote calls on the same service, I systematically get this :
java.lang.IllegalAccessError: class sun.reflect.GeneratedMethodAccessor15 cannot access its superclass sun.reflect.MethodAccessorImpl
Restarting client or service provider solves the problem. It looks like there is a limitation on number of calls on the same service.
Someone has an idea ?
Thanks in advance.

do you have a few more details of what your setup looks like? E.g. what
JDK, ECF version, Interface of your remote service... Ideally you would
file a bug report  and attach a sample project and a .launch file
that reproduces this behavior.

first of all, you are on very old version of ECF. The most recent one is
3.5.6 . Can you verify that the IllegalAccessError also shows up with
ECF current too?
Second, you say that EMF EObjects are used as parameters/return values.
Do you know if this bug appeared first, when you started using them?
Lets try to isolate technologies...
Btw. do you have the complete stack trace for the
