I found a workaround solution.
When I manually reset the cached generator result in
my ServiceInterfaceProxyGenerator the problem disappears.
public class RpcInterceptorServiceProxyGenerator extends
ServiceInterfaceProxyGenerator {
@Override
public RebindResult generateIncrementally(TreeLogger logger,
GeneratorContext ctx, String requestedClass) throws
UnableToCompleteException {
((StandardGeneratorContext) ctx).setCachedGeneratorResult(null); // reset
cached result here
super.generateIncrementally(logger, ctx, requestedClass);
// ... generate code ...
return new RebindResult(RebindMode.USE_ALL_NEW, newTypeName);
}
}
If anybody finds a better solution, please let me know. Thanks.
