Description Michael Keppler

2019-08-18 13:38:14 EDT

I see an error in multiple workbenches after upgrading to 4.13M2 pointing to the classes of bug 548058. I guess I see the error in all workbenches with Wild Web Developer installed. Not really sure if this is a platform issue or Wild Web Developer issue.

Plug-in org.eclipse.lsp4e was unable to load class org.eclipse.lsp4e.operations.symbols.WorkspaceSymbolsQuickAccessProvider.

Mickael, could you please check? Could be something we must fix for RC1?

Can you please try again woth a more recent build of Platform? Bug 548058 was fixed  in M3 and wasn't available earlier. It requires a build older than August 8th .
LSP4E snapshots that you seem to be using require a such recent build.
If you can't upgrade to Platform 4.13.M3, just downgrade LSP4E to 0.10.0 release.

Haven't seen the issue anymore on recent installations, therefore closing.
