Forked three files to make minor changes to reduce dependencies (and in the case of ResolverConfigurationImpl.java to remove the need for a map.xml hack).

/**
|
||||
* This class represents access to a file or directory. A FilePermission consists
|
||||
* of a pathname and a set of actions valid for that pathname.
|
||||
* <P>
|
||||
* Pathname is the pathname of the file or directory granted the specified
|
||||
* actions. A pathname that ends in "/*" (where "/" is
|
||||
* the file separator character, <code>File.separatorChar</code>) indicates
|
||||
* all the files and directories contained in that directory. A pathname
|
||||
* that ends with "/-" indicates (recursively) all files
|
||||
* and subdirectories contained in that directory. A pathname consisting of
|
||||
* the special token "<<ALL FILES>>" matches <b>any</b> file.
|
||||
* <P>
|
||||
* Note: A pathname consisting of a single "*" indicates all the files
|
||||
* in the current directory, while a pathname consisting of a single "-"
|
||||
* indicates all the files in the current directory and
|
||||
* (recursively) all files and subdirectories contained in the current
|
||||
* directory.
|
||||
* <P>
|
||||
* The actions to be granted are passed to the constructor in a string containing
|
||||
* a list of one or more comma-separated keywords. The possible keywords are
|
||||
* "read", "write", "execute", and "delete". Their meaning is defined as follows:
|
||||
* <P>
|
||||
* <DL>
|
||||
* <DT> read <DD> read permission
|
||||
* <DT> write <DD> write permission
|
||||
* <DT> execute
|
||||
* <DD> execute permission. Allows <code>Runtime.exec</code> to
|
||||
* be called. Corresponds to <code>SecurityManager.checkExec</code>.
|
||||
* <DT> delete
|
||||
* <DD> delete permission. Allows <code>File.delete</code> to
|
||||
* be called. Corresponds to <code>SecurityManager.checkDelete</code>.
|
||||
* </DL>
|
||||
* <P>
|
||||
* The actions string is converted to lowercase before processing.
|
||||
* <P>
|
||||
* Be careful when granting FilePermissions. Think about the implications
|
||||
* of granting read and especially write access to various files and
|
||||
* directories. The "<<ALL FILES>>" permission with write action is
|
||||
* especially dangerous. This grants permission to write to the entire
|
||||
* file system. One thing this effectively allows is replacement of the
|
||||
* system binary, including the JVM runtime environment.
|
||||
*
|
||||
* <p>Please note: Code can always read a file from the same
|
||||
* directory it's in (or a subdirectory of that directory); it does not
|
||||
* need explicit permission to do so.
