#905 IOException when saving file

[Bao N. Nguyen]

The following steps throw an exception in revision 5425

1. Start DrJava
2. Type something on text area
3. Save
4. Type random text containing "/" (e.g. "/dd/crash.java") in filename textbox
5. Click OK

A dialog box containing IOException trace will show up. I'm unable to copy the trace here because it doesn't show up in the Errors window.

Environment
OS: Ubuntu 10.10
Java: jdk-6-21

This error seems happen to almost all other Open and Save windows. For example, in Create New Project,

1. Follow Menu Project/New
2. Enter /crash/crash/crash in the project path textbox
3. OK

Exception trace:

I don't think the IOException on Save is a bug. If a user enters an invalid file, some error has to be displayed. We should omit the stack trace, though. It makes it look like a bug.

The IO operations that can be done with projects, as well as Save All, do have bugs, though. If the user enters a project file that cannot be accessed, the operation should terminate, not pop up the Project Properties window and several error windows.

I'm working on fixing both.

I'm going to pick my work on this bug up again this weekend.
