format=omni causes an infinite loop for Jackson Databind Unit Test #5

Closed takashi-ishio closed 3 years ago

takashi-ishio commented 3 years ago

Executing defects4j test for Jackson DataBind 92b resulted in an infinite loop. When a checkPermission method is called, logging code tries to record logging information. The step triggers an additional checkPermission call.

Workaround: Excluding a security manager from bytecode weaving.
