# @test
# @bug 4758537 4809833
# @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.
