fixes #12859
Background
This PR updates the grpc-servlet Undertow tests to work with Undertow
2.2.39.Finaland2.3.21.Final.Those releases changed Undertow's default
MAX_ENTITY_SIZEto 2 MiB, which causedUndertowInteropTest.veryLargeRequest()to fail before the request reached the gRPC servlet.Cause
UndertowInteropTest.veryLargeRequest()sends a 10 MiB unary request. The test server already configured gRPC'smaxInboundMessageSize, but it did not configure Undertow's container-level entity size limit.After the Undertow default changed, the container started rejecting the request and the client saw
RST_STREAM ... CANCEL.Changes
