Here are the imports for java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/code/ClassFinder.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/comp/Infer.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/main/Arguments.java.orig:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/main/OptionHelper.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/main/Option.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/main/Arguments.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/api/ClientCodeWrapper.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/file/Locations.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/file/RelativePath.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/file/JavacFileManager.java:import java.io.File; langtools/src/jdk.compiler/share/classes/com/sun/tools/javac/processing/JavacProcessingEnvironment.java:import java.io.File; We should audit the list. some may just be for File.separator or File.pathSeparator. Uses of java.io.File object (especially in conjunction with JavaFileManager) should be investigated.

For bonus points, grep javac for "java.io.File" and see if there are any other remaining references that should be updated.

Problem is these lines in javac ClassFinder: StandardJavaFileManager fm = (StandardJavaFileManager)fileManager; if (haveSourcePath && wantSourceFiles) { List<File> path = List.nil(); for (File file : fm.getLocation(SOURCE_PATH)) { path = path.prepend(file); } log.printVerbose("sourcepath", path.reverse().toString()); } else if (wantSourceFiles) { List<File> path = List.nil(); for (File file : fm.getLocation(CLASS_PATH)) { path = path.prepend(file); } log.printVerbose("sourcepath", path.reverse().toString()); } if (wantClassFiles) { List<File> path = List.nil(); for (File file : fm.getLocation(PLATFORM_CLASS_PATH)) { path = path.prepend(file); } for (File file : fm.getLocation(CLASS_PATH)) { path = path.prepend(file); } log.printVerbose("classpath", path.reverse().toString()); } Generally, all List<File> should become List<Path> (import java.nio.file.Path) and fm.getLocation should be changed to fm.getLocationAsPaths. Test program should be to use Toolbox to compile any file with -release 7 -verbose, and verify compilation is OK.

Bug! It looks like there are remaining references to java.io.File, in the code for -verbose, which need to be converted to java.nio.file.Path

This bug means users can't use the -release option in Oracle JDeveloper since -verbose is used as well to capture all Javac output so it can be filtered and used for displaying compiler progress to the user.
