Invalid project description

When I open the first class in my SAP Hybris workspace the language server starts up and then after some time outputs the following log:

[Error - 07:25:19] 26.06.2018 07:24:41 Initialization failed

It would be nice to know which project it is and what caused this

Environment

• Operating System: macOS 10.12.6 (16G1314)
• JDK version: java version "1.8.0_144"
• Visual Studio Code version: 1.24.1 (1.24.1)
• Java extension version: 0.27.0

Steps To Reproduce

See above

[attach a sample project reproducing the error] -> that's exactly the problem!!
attach logs

Current Result

Only stacktrace is printed to the console

Expected Result

Output more infos, so that the issue can be fixed.

Start at EclipseProjectImporter.importDir in EclipseProjectImporter.java, where the stack trace shows project creation failing, and trace the directory being imported. Reproduce with the reported SAP Hybris workspace and improve the diagnostic output so it identifies the project and cause of the invalid description.
