Java
System.out, broad catches, empty catches.
One of 104 modules in the GateTest scan suite. Catches the issue before it reaches code review, and on paid tiers opens a pull request with the fix already written.
Example finding from the java module
catch (Exception e) {} at OrderService.java:301Why we catch it
Nine non-JS language backends. Same engine, language-aware patterns.
The Java module sits in this category alongside 6 related modules. Together they form one of the layers of a GateTest scan — checks fire in parallel, findings cluster by root cause, and on paid tiers the AI auto-fix loop reads each finding, writes the fix, validates against the scanner, and opens a PR.
How GateTest covers java
- ✓Runs in every scan. Included on the Full ($99), Scan + Fix ($199), and Forensic Scan ($399) tiers. No additional configuration.
- ✓Free CLI.
npm i -g gatetest && gatetest --module javaagainst any local repo. No paywall on the scanning itself. - ✓AI auto-fix PR. Scan + Fix tier opens a pull request with the fix, a regression test, and a pair-review by a second Claude. Forensic Scan tier adds per-finding diagnosis and cross-finding attack-chain correlation.
- ✓Honest confidence rating. Findings come with high / medium / low confidence so noisy patterns don't block the gate. The confidence-calibrator trainer reads customer suppressions and tightens rules over time.
