This bug fix release contains an important fix

https://github.com/graphql-java/graphql-java/pull/2773

The latest 18.0 version of graphql-java changed the way raw values are resolved to canonical values.

However this revealed a bug in MaxQueryXXX instrumentation where invalid values (null being present for non nullable input values) caused an exception rather than generating a graphql error. This is not a behavior we intended.

The bug is only present if you use graphql.analysis.MaxQueryDepthInstrumentation and graphql.analysis.MaxQueryDepthInstrumentation
