Since orm/doctrine update to 2.7.3 I've got this error (issue title) when I try to serialize an collection of entities "products" get with Doctrine.

Steps required to reproduce the problem

1. findAll products with Doctrine EntityManager in Products table to get $product
2. build serializer : $serializer = JMS\Serializer\SerializerBuilder::create()->build();
3. serialize : $product = $serializer->serialize($product, 'json');
4. var_dump serialization : var_dump($product);

Expected Result (get with orm/doctrine 2.7.2)

• string(461) "[{"id":1,"price":"100.00","customer":{"id":1,"name":"Customer 1","address":"Address 1","address_extra":"Address extra 1","city":"City 1","postal_code":"75001"},"type_product":{"id":1,"code":"typeProducts1","lib":"Type product 1"}},{"id":2,"price":"200.00","customer":{"id":2,"name":"Customer 2","address":"Address 2","address_extra":"Address extra 2","city":"City 2","postal_code":"75002"},"type_product":{"id":2,"code":"typeProducts2","lib":"Type product 2"}}]"

Actual Result

• PHP notice "throw" in step 3

Hi, thanks for your report, but how am I supposed to reproduce the issue?

Hi, I'm gonna to try to be more explicit

Error

The error

Notice: Accessing static property Proxies_CG_\examplemodel\Customers::$lazyPropertiesNames as non static

occured when I try to serialize the entities collection in Test.php

[KevinMarques]

Same issue here after updating doctrine/orm from 2.7.2 to 2.7.3.

[renatko]

Same issue here. Downgrade to "doctrine/common": "2.13.*" fixed it

[jannmylj]

I have no urgency on my side for the moment.
I prefer not to set the doctrine/common version and let the dependency manager choose the best / latest version.
Is it a mistake ?

[thepercival]

yes, downgrading is the solution for now:
"doctrine/persistence": "^1.3"
or as renatko said : "doctrine/common": "2.13.*"

[waresz]

Same error after updating to doctrine 2.7.3.

-> Downgrade to 2.7.2.

[goetas]

can you please try #1210 ?

[jannmylj]

I've got expected result

string(461) "[{"id":1,"price":"100.00","customer":{"id":1,"name":"Customer 1","address":"Address 1","address_extra":"Address extra 1","city":"City 1","postal_code":"75001"},"type_product":{"id":1,"code":"typeProducts1","lib":"Type product 1"}},{"id":2,"price":"200.00","customer":{"id":2,"name":"Customer 2","address":"Address 2","address_extra":"Address extra 2","city":"City 2","postal_code":"75002"},"type_product":{"id":2,"code":"typeProducts2","lib":"Type product 2"}}]"

Good news!

Same issue with Doctrine 2.8.4. All models serialize normally, except one. If I ignore this notice, serialized model will look like this

{
            "id": 2,
            "person": {
                "__initializer__": [],
