What's Changed

• Breaking change: Remote code execution findings are no longer reported when the honeypot class jaz.Zer is initialized but not instantiated.

• Bugfix: agent: Fixed instrumentation of classes already instrumented with JaCoCo (https://github.com/CodeIntelligenceTesting/jazzer/pull/621)
• Bugfix: junit: Extende list of ignored packages to include JUnit and Mockito (https://github.com/CodeIntelligenceTesting/jazzer/pull/664)
• Bugfix: junit: Added missing dependency on org.junit.platform:junit-platform-launcher (https://github.com/CodeIntelligenceTesting/jazzer/pull/654)
• Bugfix: autofuzz: Filters out unnamed classes (https://github.com/CodeIntelligenceTesting/jazzer/pull/627)

What's Changed

• Breaking change: assert statements are no longer automatically enabled in @FuzzTests executed via JUnit as it is not possible to do so reliably. If you want your @FuzzTests to execute these statements, use the -ea JVM flag.
• Feature: @FuzzTests now use the JUnit-provided test instance, which improves support for mocks (https://github.com/CodeIntelligenceTesting/jazzer/pull/604)
• Feature: @FuzzTests executed using the Jazzer CLI now use the JUnit launcher API and thus support all JUnit lifecycle hooks (https://github.com/CodeIntelligenceTesting/jazzer/pull/612)
• Feature: The inputs directory for a @FuzzTest is now created automatically if a test resource directory exists (https://github.com/CodeIntelligenceTesting/jazzer/pull/585)
• Feature: Kotlin integer compares are now tracked (https://github.com/CodeIntelligenceTesting/jazzer/pull/593)
• Bugfix: autofuzz: Fixed handling of generic array types (https://github.com/CodeIntelligenceTesting/jazzer/pull/584)
• Bugfix: autofuzz: Fixed findings being reported when autofuzz fails to construct inputs (https://github.com/CodeIntelligenceTesting/jazzer/pull/588)
• Bugfix: autofuzz: Java reproducers enable assertions (https://github.com/CodeIntelligenceTesting/jazzer/pull/590)
• Bugfix: Added internal maven and gradle classes to custom hook excludes with JUnit (https://github.com/CodeIntelligenceTesting/jazzer/pull/601 by @florianGla)
• Native sanitizer lib location can be overriden via an environment variable (https://github.com/CodeIntelligenceTesting/jazzer/pull/606)
