Can you elaborate in more detail what happens and how to reproduce this issue? Would also be good to know whether this problems happens only if you install the STS4 pieces into Eclipse or even without that (using a plain Eclipse install).

I reproduced... yes, STS4 to blame it seems :-(

Open java.io.File and try Ctrl + mouse click on any Java type inside file

Should be fixed when this is resolved: https://bugs.eclipse.org/bugs/show_bug.cgi?id=544794

Before installation, ctrl+left can be entered the source code. ctrl+left does not display open impelementation.

I think it's fixed with https://bugs.eclipse.org/bugs/show_bug.cgi?id=544794 Mikael merged the quick fix for it rather quickly without requiring a test... Think the next STS4 eclipse nightly build would have the fix since we are targeting smapshot builds of lsp4e

Should be in the nightly builds already...

[user20161119]

Waiting for 4.2.0

[BoykoAlex]

Another option is try LSP4E project nightly build as the fix went in that project. Here is the nighly build update site: http://download.eclipse.org/lsp4e/snapshots/
