A DESCRIPTION OF THE PROBLEM :
Given a record class with a constant field,
And that constant field has an annotation,
When compiling that class,
Then the compilation throws an exception.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a record class with a field:

record RecordClass() {
    @SuppressWarnings("foo")
    private static final int FIELD = 42;
}

Compile that record class, for example, with javac --enable-preview -source 14 -target 14 RecordClass.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The record is compiled successfully into a class file.
ACTUAL -
The compiler throws a NullPointerException with the following stack trace:
$ javac --enable-preview -source 14 -target 14 *.java
Note: RecordClass.java uses preview language features.
Note: Recompile with -Xlint:preview for details.
An exception has occurred in the compiler (14.0.2). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.

CUSTOMER SUBMITTED WORKAROUND :
No general workaround is known at this time. In specific situations, like using @SuppressWarnings, tool might offer tool-specific workarounds, for example, using a warning suppression comment instead of the @SuppressWarnings annotation.
