On Windows: LanguageServer not initialized after 10s #25
Description
Hi,
I just wanted to try out the new STS4 beta version with a simple Spring Boot Demo project. But when starting Eclipse STS4 I always get the following error in the Eclipse Error Log:
LanguageServer not initialized after 10s
with the following stack trace:
java.util.concurrent.TimeoutException at java.util.concurrent.CompletableFuture.timedGet(CompletableFuture.java:1771) at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:1915) at org.eclipse.lsp4e.LanguageServerWrapper.getServerCapabilities(LanguageServerWrapper.java:488) at org.eclipse.lsp4e.LanguageServiceAccessor.getLSWrappers(LanguageServiceAccessor.java:243) at org.eclipse.lsp4e.LanguageServiceAccessor.getLSPDocumentInfosFor(LanguageServiceAccessor.java:354) at org.eclipse.lsp4e.ConnectDocumentToLanguageServerSetupParticipant$1.run(ConnectDocumentToLanguageServerSetupParticipant.java:74) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:56) And in the progress window the "Initialize Language Servers for DemoApplication.java" task hangs forever.
For installation I downloaded the "Spring Tools 4 for Eclipse" distribution and created an empty workspace without any additional customization:
Spring Tool Suite 4
Version: 4.0.0.M6
Build Id: 201711271125
My Eclipse is started with :
java.version=1.8.0_121
java.home=D:<JDK_HOME>\jre
If I understand it correctly Eclipse should start the Spring Boot Language Server but I guess this somehow fails. But I have no idea why or where I should look for further information. In the Eclipse workspace log I only see these log messages:

The new "Runtime information in your editor" features looks really cool and I can't wait to try it out on my machine :-)
Thanks and regards,
