Problem with BuiltInDS (HSQLServletContextListener class not found)

[Blama]

Hi Isomorphic,

I'm trying to prepare a testcase (v9.1p_2014-09-12) and found that BuiltInDS does not start any more. Did you change anything here recently (since 8th Sep 2014 most likely) that could have caused this error?

Server Log:

I did a build.xml->libs and started then in GWT 2.6.1 Development Mode with Eclipse Luna.
SGWTEE_HOME\lib\hsqldb-2.2.9.jar is in the build path and the file is available in the file system.

Best regards,
Blama

There's been no relevant change - this just looks like the .jar isn't there, despite you having checked on it. It might be not readable to the Servlet engine (eg, owned by root and not readable by other users) or corrupt.
