Java (TM) 2 Runtime Environment, Standard Edition Version 1.4.2 The Java(TM) 2 Runtime Environment contains the Java virtual machine, runtime class libraries, and Java application launcher that are necessary to run programs written in the Java programming language. It is not a development environment and does not contain development tools such as compilers and debuggers. For development tools, use the Java 2 SDK, Standard Edition. Flavors: native_bootstrap Bootstrap the jdk using a previously built and installed devel/jdk/1.4 package. NOTE: if this flavor is used without a previously installed devel/jdk/1.4 package, the port will build the jdk twice! no_plugin The Mozilla plugin is not built. no_webstart Java Web Start (javaws) is not built. with_ipv6 Build the jdk/jre with ipv6 support. When the jdk/jre is built with this flavor, java will create only ipv6 sockets by default. Since ipv4 to ipv6 address mapping is disabled on OpenBSD, using ipv4 addresses will fail. Consenquently, you may only use ipv6 addresses or you can start java with -Djava.net.preferIPv4Stack=true and can only use ipv4 addresses.
