Last week I encountered what is probably a related issue, being that IB significantly changed the TWS release format between 952 and 953. They refer to this in the version 953 release notes as the .

Version 952 and earlier were available as smallish (~53 MB) JARs, whereas now they release large (~123 MB) operating system specific Install4J installers. These installers embed a specific JRE release. Unfortunately IB still do not version the standalone install URLs, nor even provide a way to determine the version number without running the installer. I can see the merit of the change for most of their users, but this new launcher approach imposes inconvenience if you run automated solutions to monitor version numbers, package TWS or unattended install TWS/IB Gateway.
