      > Task :gnd:compileDebugJavaWithJavac FAILED

      A DESCRIPTION OF THE PROBLEM :
      When attempting to build our project using javac version 1.8.0_181 I get the following error:

      An exception has occurred in the compiler ((version info not available)).
      java.lang.NullPointerException
      at com.sun.tools.javac.comp.Flow$FlowAnalyzer.visitApply(Flow.java:1233)

      The build is run on the Google Cloud Platform. Build details here: https://pantheon.corp.google.com/cloud-build/builds/f87de61d-ffa3-4092-861b-2b0a1971b11c;step=3?project=ground-android-gcb

      It is an Android project written in Java. We started seeing this error after making these code changes: https://github.com/google/ground-android/pull/617/files

      Notably we added the ErrorProne and NullAway plugins to our project. I wonder if there's something in there which the compiler doesn't like.

      This issue looks almost identical: https://bugs.openjdk.java.net/browse/JDK-8237565

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1) Open a browser here: https://pantheon.corp.google.com/cloud-build/builds/f87de61d-ffa3-4092-861b-2b0a1971b11c;step=3?project=ground-android-gcb
      2) Click "Retry"



      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Either compilation fails with useful error message or compilation succeeds.
      ACTUAL -
      Compiler throws NullPointerException
