What steps will reproduce the problem?

  1. write a Java class with lombok annotations and a method containing a '+=' assignment. In the attached tgz in File src/exp/ASimpleValue.java line 13 you can see the example
  2. run delombok on the source file

What is the expected output?

expected output is the 'delomboked' code at the end of the source file, the body of the method getCalculatedValue() should be unchanged

What do you see instead?

delombok makes the line
ret += 1;
to
ret = 1;

(in attached tgz it is the file src-delomboked/exp/ASimpleValue.java line 9)

What version of the product are you using? On what operating system?

  • lombok v1.1.12
  • Output of java -version:
    java version "1.7.0_25"
    OpenJDK Runtime Environment (fedora-2.3.12.1.fc17-x86_64)
    OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
  • Operating System: Fedora 17, Kernel 3.9.10-100

Yup, dang. I thought we had a test for this; we broke this during the modifications to handle new code in javac8.

Well, we have tests for it now, and this issue has been fixed.

Edge release is here: https://projectlombok.org/download-edge.html

We'll probably release a new official version quite soon; this is a major issue that shouldn't be in a stable release.

@lombokissues lombokissues added this to the 1.12.4 milestone Jul 14, 2015
