IntelliJ IDEA is the top Java and Kotlin IDE by JetBrains, a software company. The author of Fernflower Java decompiler, Stiver, recently passed away after battling glioblastoma. Stiver developed a groundbreaking decompiler due to limitations in existing options and took a unique approach to creating his own. After gaining popularity, Fernflower was integrated into IntelliJ IDEA by JetBrains in 2014, thanks to Stiver’s agreement to open-source the tool. Stiver’s work revolutionized Java development by providing a highly effective decompiler that saved developers valuable time while debugging. His legacy lives on through the continued improvements to Fernflower by the JetBrains Java team.
