Error on running Auto tuning

[aabhasb]

I tried to run the auto-tuned mode by using a combination of line based and structured. I was performing my experiments over the curated DrJava source code made available from the first JDime evaluations. I was running the tool in the following manner - "JDime -r -m linebased,structured -f -o mergeDir LeftDIr BaseDir RightDir "

I keep getting the following error:
java.lang.RuntimeException: beaver.Scanner$Exception: illegal escape sequence "'\u"
at de.fosd.jdime.util.parser.Parser.getTokenCount(Parser.java:184)"
As a result of this error, the tool falls back to line based approach "JDime [20:05:28] SEVERE: Falling back to line based strategy. "

I thought this is a windows issue and how it uses "" for directory separators so I tried the same command in Linux and through Eclipse by using "\" but I kept getting the same error. Oddly, this does not happen when I pass either only linebased or only structured as the mode.

Attached is the stack trace

Alright, so when using the combined strategy (-m A,B) the code resulting from using strategy A is parsed to determine whether there were conflicts and strategy B needs to be tried. This parsing is done as part of statistics collection and thus includes having ExtendJ count the number of tokens in the code. That fails in ExtendJ, not in our code. Apparently the merge result contains character escape sequences that ExtendJ can't handle.

Could you please attach the directories that you were merging? Might be that a more recent ExtendJ version resolves the issue.

I tried running Jdime from CMD and from bash shell. Hence, I passed the following directories respectively:
D:\mergedProjects\completed\DrJava\rev3734-3786\base-trunk-3734
/mnt/d/mergedProjects/completed/DrJava/rev3734-3786/base-trunk-3734$

Also, I noted the combined strategy works when I work on a single file, it fails when I use the '-r' option for a recursive merge.
