1.9.3 (22 November 2017, bugfix release)

• Fixed a severe bug that was caused by a breaking change in IntelliJ (no UI allowed during file change events, see the corresponding IntelliJ change on GitHub and that led to IntelliJ crashing when files contained in the VFS were deleted, moved or renamed in the IntelliJ
  project (internal tickets MCMS-64, MCMS-66).
• Fixed multiple exceptions that occurred after IntelliJ introduced concurrent module initialization (previously modules were initialized sequentially) because the plugin's OpenCms module initialization code was not thread safe. Now OpenCms modules are initialized only after all IntelliJ modules are initialized.
