Akhilesh Singh commented on NETBEANS-5069:
------------------------------------------
After analysis and complete investigation found the issue is with the latest
release of lombok(i.e. 1.18.16), this release unable to resolve the correct
owner-kind for any variable(defined by the annotation @RequiredArgsConstructor
and @setter) on the fly.
*Problematic area*
Consider the below code snippet
{color:#0747a6}_package net.ponec.junitlombok;_{color}
{color:#0747a6}_import lombok.Setter;_{color}
{color:#0747a6} _@Setter_ {color}
{color:#0747a6}_public class Bean {_{color}
{color:#0747a6} _private Integer id;_{color}
{color:#0747a6}_}_{color}
Will convert to the following after process the annotation @Setter
{color:#0747a6}_package net.ponec.junitlombok;_{color}
{color:#0747a6}_import lombok.Setter;_{color}
{color:#0747a6} _@Setter_ {color}
{color:#0747a6}_public class Bean {_{color}
{color:#0747a6} _private Integer id;_{color}
{color:#0747a6}_void setId(final Integer id){_{color}
{color:#0747a6}_this.setId = id;_{color}
{color:#0747a6}_}_{color}
{color:#0747a6}_}_{color}
As per the compilation process, the owner for the method param variable "final
Integer id" is the method "setId" of type MTH. But lombok(1.18.16) considering
this as a null of type NIL. PFB screenshots

Due to the problem of incorrect owner-kind(NIL) the variable "final Integer id"
is not trackable via nbjavac-15 and its setting the address -1 for this
variable. And the compilation of class *Bean* is not successful. The classes
that's uses the Bean class showing compilation error. The example attached in
this defect used @RequiredArgsConstructor annotation, for this owner-kind for
the variable "final Integer id" is Constructor of type MTH coming as a NIL.
Same is not happening with the lombok versions below 1.18.16. Below analysis
performed using lombok 1.18.12

!image-2021-01-11-19-11-33-670.png!
As lombok 1.18.12 processing the annotation @Setter correctly the owner-kind as
MTH for the variable "final Integer id", so there is no problem with the
compilation.
Tested some other annotations also like @Getter and @toString that's working
fine with this version 1.18.16 because there no parameter required to pass for
the method signature *getId(){}* & *toString(){},* so no owner-kind variable
concept exist here.
