Hi,
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.

Hi Ben,
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 [1] and attach a sample project and a .launch file
that reproduces this behavior.
Thanks

Hi Ben,
first of all, you are on very old version of ECF. The most recent one is
3.5.6 [1]. 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
java.lang.IllegalAccessError?
Thanks
Markus
