Server launch causes java.lang.AbstractMethodError

[jeffmaury]

Installed the latest 1.6.1 and tested my Quarkus LSP (github.com/redhat-developer/intellij-quarkus). When the server is launched, I have the following error:

java.lang.AbstractMethodError: com.intellij.openapi.wm.StatusBarWidget.getPresentation(Lcom/intellij/openapi/wm/StatusBarWidget$PlatformType;)Lcom/intellij/openapi/wm/StatusBarWidget$WidgetPresentation;

I am using IU-2019.1 and noticed StatusBarWidget does not have the empty parameter getPresentation method. It is there on 2019.3, so seems this plugin is not compatible with older releases.

That's pretty bad indeed, I've uploaded a release for earlier versions and also uploaded it on the JetBrains repository. I hope it will fix your problems.
