Diffblue Cover was unable to write a Spring test, F009 Internal error.

java.lang.reflect.InaccessibleObjectException: Unable to make field transient java.util.regex.Pattern$Node java.util.regex.Pattern.root accessible: module java.base does not “opens java.util.regex” to unnamed module @293a5bf6

Hi @reda

Thank you for reporting this exception; we will pass it onto the engineering team to investigate further

Is Diffblue Cover working fine for you otherwise? Is there anything else we can do to help?

Kind Regards

Matt @ Diffblue
