   This is reproduce, although it took time on my notebook. I activated more `On Save` actions (in the Options `Editor` -> `On Save`). It shows as a classic EDT block, i.e. the main window does not repaint anymore.
   
   From that stacktraces @syco provided, I think we see a deadlock, because the EDT holds either a read or write lock on the document and tries to invoke the ParserManager, while the Thread named `ModuleActions` is the already executing a task in the ParserManager and then tries to write lock the document.
   
   When I managed to reproduce this, in the output I see the most probably right hint:
   
   > WARNING [org.netbeans.modules.parsing.impl.TaskProcessor]: ParserManager.parse called in AWT event thread by: org.netbeans.modules.micronaut.hyperlink.MicronautJavaHyperlinkProvider.getPropertyName(MicronautJavaHyperlinkProvider.java:151)
   
   @dbalek could you please have a look at this? Is there a way to not jump into the `ParserManager` when the hyperlink provider is used? Maybe gathering the information can be moved of the EDT and then used from the EDT.
