Я загрузил последнюю версию dr. java - а также jdk-14.01_windows-x64_bin.exe и jdk-14.01_windows-x64_bin.zip Я также пробовал использовать openjdk-8 и пытался запустить dr. java.
Dr java может нормально работать и компилироваться, но всякий раз, когда я пытаюсь использовать отладчик, я получаю ошибку, описанную ниже.
Я пытался изменить путь к tools.jar, чтобы он указывал на папку jdk, но это не так. похоже, не работает. Мне не удалось найти tools.jar. Я использую Windows 10 в 64-битной операционной системе.
