IntelliJ 2019.2.2 plugin crashes (NullPointerException)

[gertvdijk]

Environment: Ubuntu 18.04, OpenJDK-8, project: gerrit branch master (currently @ ac917a921173a23cf8fb01ab16d8aacd9f9bf376).

Steps to reproduce:

1. Recursive clone of Gerrit Code Review:

   $ git clone https://gerrit.googlesource.com/gerrit
   $ cd gerrit
   $ git checkout ac917a921173a23cf8fb01ab16d8aacd9f9bf376
   $ git submodule update --init
   

2. Install IDEA Ultimate 2019.2.2

3. Install Bazel plugin (currently offered: 2019.08.19.0.5)

4. Configure Bazel plugin to use Bazelisk binary (or install Bazel 0.29.1 or 1.0.0rc2, happens with both, and make sure it's on PATH).

5. Import Bazel project (Gerrit) via project view file .bazelproject.

6. Fully sync project.

7. Observe IDE error message. Stacktrace attached: bazel-plugin-stacktrace.txt

All works fine with 2019.1.x (which will then offer an older Bazel-IntelliJ plugin), and then making sure Bazel version is 0.29.1 instead of 1.0.0rc2 via Bazelisk.

Another project (internal) runs perfectly fine with the same IntelliJ configuration. So, it's probably something in the Gerrit code base triggering this (a warning of some sort, as problems.BlazeProblemsView.createToolWindow in the traceback indicates).

Via #1166, also fixes the NPE for me. Apparently this is fixed @ HEAD, but unreleased.
