Workbench internal error while opening notebooks (update)

Update: Are those session parameters incorrect for a 64-bit environment?

I have Mathematica 10.3 installed on my work Windows 7 (64-bit) computer, and Workbench was downloaded and installed last week. When I attempt to open any notebook within the workbench, I get this:

An internal error occurred during: "FrontEnd Job::Open Notebook".

Session Data:
    eclipse.buildId=unknown
    java.version=1.6.0_05
    java.vendor=Sun Microsystems Inc.
    BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
    Command-line arguments:  -os win32 -ws win32 -arch x86

The Eclipse version is apparently 3.5.1.

I did not perform the installation myself (I do not have admin.) I would check the system requirements if I could find them listed somewhere.

Help in getting it working would be appreciated.

I had the same problem. I mailed wolfram with the kind request to send me Workbench 3, and so they did. Solved some of the problems between Workbench 2 and Mathematica 10.3+.

Still it would be nice to have a new release of workbench (which they probably use internal...)

Agreed. Workbench 2 is many years old, which makes it unsuitable as an IDE when developing substantial Wolfram language applications in a group. Wolfram developers have confirmed that they use a more recent version internally, and that it is mainly a matter of packaging and publishing this version in order to make it publicly available. Doing so is important since it would make the transition from front end-based to IDE-based development much easier.

Same problems here.
