Please review a small fix to the source launcher that showed up as the launcher sometimes ignoring the --source option and finding/running a class on the class path.
The problem occurs when the classpath is set after the --source option, causing LM_CLASS mode to override the setting of LM_SOURCE. In addition, some of the error messages that may be reported by the source launcher are improved to use "source file" instead of "file" as an indication that source-file mode is being used.
