Before meeting a very distressing problem, jmeter link database, the database to fill in all the information there is no problem, jmeter on another computer can be a normal link, but on my computer but not always result,
Mysql database also links with all normal, I could not find the cause. View error information,
Jmeter thought it was the wrong version, then again for a few jmeter version, the final or not.
Finally see my jdk version, originally my jdk version mismatch cause, my jdk version is 1.7, probably due to the 1.7 jdk incompatible in some places, and later replaced jdk 1.8 and later, download jmeter, after running it Normal.
