啟動JMeter 3.2的時候，發(fā)現(xiàn)JMeter的日志里報異常澜薄，異常信息為無法找到keytool，而之前的版本并沒有這個問題：

經(jīng)過網(wǎng)上搜索，發(fā)現(xiàn)已經(jīng)有人給JMeter報了bug茅特，項目的人答復(fù)在這里忘分。大意是說這個不是個問題，因為JMeter會有多種方法嘗試找到keytool白修，最終JMeter會從JAVA_HOME變量里找到keytool妒峦，不會影響正常使用，他已經(jīng)把該日志的級別從“Error”降到“Info”兵睛，將來的版本就不會有該問題了肯骇。

如果你是個潔癖，無法忍受這個異常祖很，可以參照這個回答累盗，把keytool所在的目錄加到PATH環(huán)境變量就可以了。
