# @summary Test that javac and java find files in similar ways

# @author Martin Buchholz

#

# @run shell/timeout=600 MineField.sh

# To run this test manually, simply do ./MineField.sh

#----------------------------------------------------------------

# The search order for classes used by both java and javac is:

#

# -Xbootclasspath/p:<path>

# -endorseddirs <dirs> or -Djava.endorsed.dirs=<dirs> (search for jar/zip only)

# -bootclasspath <path> or -Xbootclasspath:<path>

# -Xbootclasspath/a:<path>

# -extdirs <dirs> or -Djava.ext.dirs=<dirs> (search for jar/zip only)

# -classpath <path>, -cp <path>, env CLASSPATH=<path>

#

# Peculiarities of the class file search:

# - Empty elements of the (user) classpath default to ".",

#   while empty elements of other paths are ignored.

# - Only for the user classpath is an empty string value equivalent to "."

# - Specifying a bootclasspath on the command line obliterates any

#   previous -Xbootclasspath/p: or -Xbootclasspath/a: command line flags.

#

# JDK 9 update:

#   java: The java launcher does not support any of the following:

#       * -Xbootclasspath/p: -Xbootclasspath:

#       * -endorseddirs -Djava.endorsed.dirs

#       * -extdirs -Djava.ext.dirs

#       All test cases exercising these features have been removed.

#   javac: The following features are only supported when compiling

#       for older releases:

#       * -Xbootclasspath/p: -Xbootclasspath: -bootclasspath -Xbootclasspath/a:

#       * -endorseddirs -Djava.endorsed.dirs

#       * -extdirs -Djava.ext.dirs

#       All test cases exercising these features have been modified to

#       use -source 8 -target 8.  In addition, javac test cases involving

#       use of the runtime properties java.endorsed.dirs and java.extdirs

#       (by means of -J-Dname=value) have been removed.

#       Although the primary purpose of the test cases in this file is to

#       compare javac and java behavior, some tests remain for javac for

#       which there is no java equivalent. However, the cases remain as useful

#       test cases for javac handling of the paths involved.
