Quotes stripped from launching arguments [message #699993]

I've upgrade to Eclipse 3.7 from 3.6.1 and ran into an issue with quotes getting stripped from the launch arguments.

For example I added the VM Argument -Dblah="hello world" to the All Platforms tab on the Launching tab of a product file. Then launched the product from the Overview tab. It fails with a java.lang.NoClassDefFoundError: world. Looking at the generated launch configuration the quotes around hello world are missing.

I have also tested with with the Program Arguments field, added --blah "hello world". After launching it from the Overview tab, the generated launch configuration is missing the quotes.

I've attached the product file with the two launcher argument changes. The product file was created from the Hello RCP Plug-in Project template.

Looked into the further and found org.eclipse.pde.internal.ui.launcher.LaunchAction.concatArgs() is stripping the quotes. Looked at the CVS history and the previous release was not using DebugPlugin.parseArguments() to concatArgs together.

DebugPlugin.parseArguments is where the quotes are getting stripped. See code below an an example.

String userArgs = "-Xms40m -Xmx384m -Dblah=\"hello world\" -Dyep=\"asdf\"";
String[] parseArguments = DebugPlugin.parseArguments(userArgs);
for (String string : parseArguments) {
 System.err.println(string);
}

The output from the above is:

-Xms40m
-Xmx384m
-Dblah=hello world
-Dyep=asdf

I'm going to file a bug about this issue.
