Java 8 has become more picky requiring classes that are indirectly referenced during compilation. Probably as a result of new type inference features. See here for a discussion: http://stackoverflow.com/questions/26799874/java-8-interface-class-loader-changes As a result dev-java/ant-apache-xalan2 fails to compile because the class org.apache.xml.serializer.SerializerTrace can't be found. That package lives in dev-java/xalan-serializer, which isn't required by dev-java/ant-apache-xalan2. Reproducible: Always Steps to Reproduce: 1. Set your system JVM to Oracle's Java 8. 2. Try to emerge dev-java/ant-apache-xalan2 The error message: >>> Compiling source in /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2 ... * Disabling all optional ANT_TASKS Buildfile: /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build.xml check_for_optional_packages: prepare: [mkdir] Created dir: /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build [mkdir] Created dir: /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build/classes [mkdir] Created dir: /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build/lib [copy] Copying 8 files to /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build/classes [copy] Copying 2 files to /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build/classes build-dep: [javac.ant] Compiling 1 source file to /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build/classes [javac.ant] /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/src/main/org/apache/tools/ant/taskdefs/optional/Xalan2TraceSupport.java:46: error: cannot access SerializerTrace [javac.ant] ((TransformerImpl) t).getTraceManager().addTraceListener(tl); [javac.ant] ^ [javac.ant] class file for org.apache.xml.serializer.SerializerTrace not found [javac.ant] 1 error BUILD FAILED /var/tmp/portage/dev-java/ant-apache-xalan2-1.9.2/work/apache-ant-1.9.2/build.xml:537: Compile failed; see the compiler error output for details.
