[Bug classpath/32516] New: gjar may create "." directory into the root of the archive

[anssi dot hannula at gmail dot com]

When specifying the archived file prefixed with './', gjar will actually create
a directory '.' inside the archive and place the file there. This breaks tools,
including gij, as obviously the root should directly contain the classes.
Trying to archive the current directory by using "." is also affected.
This works correctly with sun jar, fastjar, and zip, as seen below:

$ jamvm -Xbootclasspath/p:"$(pwd)/tools/tools.zip" gnu.classpath.tools.jar.Main
-cf classpath.jar ./COPYING
$ /usr/lib/jvm/java-sun/bin/jar -cf sun.jar ./COPYING
$ fastjar -cf sun.jar ./COPYING
$ zip zip.jar ./COPYING
  adding: COPYING (deflated 62%)

$ unzip -l classpath.jar
Archive:  classpath.jar
