[ajdt-dev] Problem with German umlauts in case-tags (AspectJ 1.6.3) 
Hi list,

i've run over some problems when using german umlauts in a case tag.
Using this code-snippet:

		StringBuffer sb = new StringBuffer(100);
		for (int i = 0;  i < in.length();  i++) {
			int c = in.charAt(i);
			switch (c) {
			case 'ä':
				sb.append("(4a)");
				break;
			case 'ö':
				sb.append("(b6)");
				break;
			case 'ü':
				sb.append("(bc)");
				break;
			case 'Ä':
				sb.append("(84)");
				break;
			case 'Ö':
				sb.append("(96)");
				break;
			case 'Ü':
				sb.append("(9c)");
				break;
			case 'ß':
				sb.append("(9f)");
				break;
			default:
				sb.append((char)c);
			}

i get this error:

If i change the cases to something like

			switch (c) {
			//case 'ä':
			case '\u00e4':
				sb.append("(4a)");
				break;
the code compiles.

To make it even more odd, if i compile my project in eclipe (with the
modified unicode-tags), i get the following error:

An internal error occurred during: "Delete and update AspectJ markers
for HEAD".

with this stacktrace:

I'm not sure if the two are related because the second error (the one in
eclipse) gives no hint in which file the error occurs. I suppose it's
when weaving aspects from an external jar, but the same jar and the same
code compiles in an ant-task without any problem.

Any hint where i could investigate further?


Cheers

Dirk
