Seeing this when trying to update AndroidX to lint 31.8.0-alpha08 from 31.8.0-alpha06. Assuming this is related to b/370778975.

When an incorrect constant is used for an IntDef, and the constant was defined using the int shift operator, the lint error is appearing on the constant definition instead of the usage.

Repro example:

import androidx.annotation.IntDef;

public class TestFlags {
    public static final int SHIFT_FLAG = 1 << 1;

    @IntDef(flag = true, value = { 0 })
    public @interface FlagDef {}

    @FlagDef int flags = SHIFT_FLAG;
}

Instead of a lint error appearing on the flags = SHIFT_FLAG line, it instead appears on the definition of SHIFT_FLAG:

  TestFlags.java:22: Error: Must be one or more of: 0 [WrongConstant]
      public static final int SHIFT_FLAG = 1 << 1;
                                           ~
  TestFlags.java:22: Error: Must be one or more of: 0 [WrongConstant]
      public static final int SHIFT_FLAG = 1 << 1;
                                                ~
