Support for javac source and target options for the 1.5 platform and earlier should be removed.
The javac command no longer support -source or -target options below 6/1.6. However, older class files are still readable by javac. Source code for older release can be ported to the newer source level. To generate class files usable by older release, a javac from a previous release train can be used.
langtools tests cover all these changes.
