It has an entirely different workflow than normal debugger (which was designed for assembler in 1972). You'll see all method calls simultaneously and can drill down into call trees where needed, inspect argument and return values (including arrays and complex objects) or drop down to source-lev

Java用のデバッガーツール。実行全体を記録して後から詳細をドリルダウンできたり音楽プレイヤーのように時間をスライダーで操作してデバッグできる。何これすごそう。
