semantic token highlights cause broken highlighting in java editor

[martinlippert]

Sometimes, semantic highlighting in the Java editor is broken when running the Spring Tools as a runtime workbench (using the latest from main and the latest from the snapshots as target platform). Not sure when and how exactly this happens, but I see these error messages appear in the runtime workbench log:
