Events are not grouped in we have proxy classes

we are using Sentry as a service and running Sentry (sentry java sdk 3.1.1) in Java in Play Framework
We are experiencing the issue that all proxy-enhanced classes are not grouped automatically in the events because hash of proxies is different.
e.g. these two events are not grouped together: see screenshots

Is there any workaround rather then manual grouping to have it out of the box, as the issue occurs for almost every event and makes Sentry quite useless for us
