1.8.0_431 is not a valid version

[ren-142326]

I manually installed oracle's jdk8U431, but I couldn't name it [email protected]_431
"" This character does not seem to pass the version number specification check,

When I replace "" with "-", the version number is verified,

But java -version outputs 1.8.0_431

So I hope "_" is also the correct version number character
