You are using 5.0.5? I believe 5.0.6 has a fix for this, wherein the
method invocation order is by number of parameters, decreasing.
You may have to do:
Object onActivate(Object[] context)
{
...
}
And check the context count explicitly, and convert the context values
explicitly, if you are on 5.0.5.
