@kuronekochomusuke do you think this should wait until we figure out the cause of the xsteam errors, or should this be pushed on its own?

[kuronekochomusuke]

I am think maybe the other error caused the xstream one. it looks like EnumMap is in the allow list

or they are not setting the jvm parameters correctly when they launch it.

I created #6326 so we can see in the log in the future if they are setting the jvm parameters correctly
