When running aspectj within Eclipse 3.0 (M9) and adding -Xmn256M as a compiler
option, the following message occurs:

"directory does not exist: -Xmx256M"

When specifying the maximum memory to use using -X="mx256M" the following
message appears:

"directory does not exist: mx256M"

This message also appears using the command line.

When doing the following command -- there is no reference maximum memory usage.

AspectJ Compiler

	Usage: <options> <source file | @argfile>..

AspectJ-specific options:
	-inpath <list>      use classes in dirs and jars/zips in <list> as source
	                    (<list> uses platform-specific path delimiter)
	-injars <jarList>   use classes in <jarList> zip files as source
	                    (<jarList> uses classpath delimiter)
	                    deprecated - use inpath instead.
	-aspectpath <list>  weave aspects from <list> zip files into sources
	                    (<list> uses classpath delimiter)
	-outjar <file>      put output classes in zip file <file>
	-argfile <file>     specify line-delimited list of source files
	-incremental        continuously-running compiler, needs -sourceroots
	                    (reads stdin: enter to recompile and 'q' to quit)
	-sourceroots <dirs> compile all .aj and .java files in <dirs>
	                    (<dirs> uses classpath delimiter)
	-emacssym           generate .ajesym symbol files for emacs support
	-Xlint              same as '-Xlint:warning'
	-Xlint:<level>      set default level for crosscutting messages
	                    (<level> may be ignore, warning, or error)
	-Xlintfile <file>   specify properties file to set per-message levels
	                    (cf org/aspectj/weaver/XlintDefault.properties)
