Amazon Q Developer issues we find in Java projects
Problems specific to Amazon Q Developer's code generation patterns when building Java apps.
Overly permissive IAM policies generated with wildcard actions and resources
Amazon Q often generates IAM policies with `*` wildcards for actions or resources as a starting point, which violates the principle of least privilege. These policies should be scoped to specific actions and resource ARNs before being applied in production.
Lambda cold start latency not addressed in generated function configurations
Generated Lambda functions use default memory and timeout settings without considering cold start impact. Functions with heavy initialization code (loading models, establishing DB connections) need provisioned concurrency or memory tuning, which Amazon Q does not configure.
Generated CDK code creates AWS resources without cost estimation or tagging
Amazon Q CDK suggestions deploy resources without cost-tracking tags or budget guardrails, making it easy to inadvertently provision expensive resources (NAT gateways, multi-AZ RDS instances) without visibility into the cost impact.
DynamoDB access patterns generated without consideration for partition key hot spots
Generated DynamoDB table designs and query patterns sometimes use partition keys that distribute poorly under load — such as a status field with few values — creating hot partitions that throttle at scale.
Java issues we check for
Common Java problems that affect production readiness.
SQL injection via string concatenation
Building SQL queries with string concatenation instead of PreparedStatement or parameterized JPA queries, allowing attackers to manipulate database operations.
Missing input validation
Controller endpoints accept request bodies without Bean Validation annotations (@Valid, @NotNull, @Size), allowing malformed data into business logic.
Thread safety issues
Mutable shared state accessed from multiple threads without synchronization, volatile, or concurrent collections — causing race conditions in production.
Resource leaks
Database connections, streams, and file handles opened without try-with-resources, leading to connection pool exhaustion and OutOfMemoryErrors.
