0.8.15

New Features

• JaCoCo now officially supports Java 26 (GitHub #2076).
• Experimental support for Java 27 class files (GitHub #2004).
• Compatibility methods generated by Kotlin compiler for functions defined in interfaces are filtered out during generation of report (GitHub #1905).
• Compatibility methods generated by Kotlin compiler for exposed boxed inline value classes (JvmExposeBoxed annotation) are filtered out during generation of report (GitHub #1944).
• Methods generated by the Kotlin compiler for functions with JvmStatic annotation are filtered out during generation of report (GitHub #2097).
• Improved filtering of bytecode generated by Kotlin compiler for when expressions and statements with kotlin.String subject where first branch condition contains string with largest hash (GitHub #2098).
• Part of bytecode that javac versions from 24 to 26 generate for switch statements and expressions with selector expression of type java.lang.String inside lambdas is filtered out during generation of report (GitHub #2023).
• Improved performance of Kotlin files analysis by parsing SMAPs only once per class (GitHub #2114).
• For better performance agent output methods tcpclient and tcpserver use BufferedOutputStream to write execution data to socket. Maven plugin, Ant tasks, CLI, API usage examples, and ExecDumpClient API use BufferedInputStream to read execution data from socket. Third-party integrations should do the same to benefit from this change in agent (GitHub #2089).

Fixed bugs

• Fixed processing of Kotlin SMAP in synthetic classes (GitHub #1985).
• Multiple JaCoCo runtimes within one JVM writing to the same output file should not cause data corruption when running on JDK versions from 6 to 10 affected by JDK-8166253 (GitHub #2065, #2074).
• For better performance agent writes to output file via BufferedOutputStream, this fixes regression introduced in version 0.6.2 (GitHub #2073).
• Fixed NullPointerException when JaCoCo agent is loaded by non system class loader, for example when loaded by JBoss Modules (GitHub #1651).
