Smarter debugging in the IDE
summary
An Eclipse Java debugger demo uses a small boat-hire app to show concrete tactics: change an object's age to 35 with drop to frame and edit value to avoid restarting, add a detail formatter and watchpoint to find who overwrites the name (Lombok complicates locations), use toggle trace point to log boat names (Titanic vs Oceanic), run code in the debug shell to construct a Person, detect a deadlock with show monitors/highlight deadlocks (locks on instance IDs 27 and 34), and remotely attach to another Eclipse; all techniques work live.
