Run jdb with command line COMMAND-LINE in a buffer.
The buffer is named "*gud*" if no initial class is given or
switch is given, omit all whitespace between it and its value.
See `gud-jdb-use-classpath' and `gud-jdb-classpath' documentation for
information on how jdb accesses source files. Alternatively (if
`gud-jdb-use-classpath' is nil), see `gud-jdb-directories' for the
original source file access method.
For general information about commands available to control jdb from gud, see `gud-mode'. (fn COMMAND-LINE)
