How should I approach a Java upgrade?
An upgrade needs a compatibility check, a tested release and a recovery path. Which changes deserve particular attention before the new version reaches production?
What needs backing up or preserving in Java?
Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
What should I check first when Java fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
How should I handle configuration and secrets in Java?
Configuration must be available to the application without exposing credentials in source control, logs or browser code. What belongs in the runtime and which access controls matter?

Use application metrics and a profiler such as Java Flight Recorder to identify CPU, allocation, locks or I/O bottlenecks. Compare steady-state performance after warm-up. Tune garbage collection based on latency and throughput goals rather than copying flags from a different workload.
