Java troubleshooting steps

Check JVM logs

Review Java Virtual Machine (JVM) logs for errors, warnings, and garbage collection (GC) activity.
Monitor memory usage

Analyze heap and non-heap memory to identify memory leaks or out-of-memory (OOM) errors.
Verify thread usage

Ensure threads aren't getting stuck or blocked, leading to performance bottlenecks.
Inspect GC performance

Check if frequent or long GC cycles are affecting performance.
Review the database connection pool

Ensure the connection pool is properly configured to avoid exhaustion or overconsumption.
Analyze stack traces

Review stack traces in exception logs to identify problematic code paths or third-party libraries.
Check dependency conflicts

Ensure that no dependency conflicts (JAR version mismatches) are causing runtime issues.
