> 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

Reply received from submitter ���========================= Just wanted to thank you for your quick response. We found a workaround by updating to openjdk13.

Requested more information from the submitter ===================================== The reproducer provided by you at https://pantheon.corp.google.com/cloud-build/builds/f87de61d-ffa3-4092-861b-2b0a1971b11c;step=3?project=ground-android-gcb is not accessible for us as it redirects to google SSO. So we are not able to reproduce it. Looking at the issue, I found this issue was reported before and was fixed in JDK 15 b01. https://bugs.openjdk.java.net/browse/JDK-8235564 Please see if this fixes the issue, and revert if any more queries are there.
