inconsistent format of version string

[Eskibear]

The context is, we parse output of java -version to determine the version of Java.

Now we have an issue reported by @RohanIRathi in microsoft/vscode-java-pack#309 (comment)
When executing java -version, the output was:

openjdk 11.0.6 2020-01-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.6+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.6+10, mixed mode)

Note that in the first line, 11.0.6 was not quoted, and there was no "version" (literally) before it.

To make it clear, you can compare it with below output, which is from my machine.

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.6+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.6+10, mixed mode)

I believe the version string should follow some convention or a certain format, and will it be different on different machine? Could that be a potential bug?

Looking into this

[adam-thorpe]

The correct convention is openjdk version "11.0.6" 2020-01-14 which shouldn't differ. I downloaded the JDK 11.0.6 windows build from https://adoptopenjdk.net and it outputs the correct java -version information. @RohanIRathi could you comment on where you got this jdk from or perhaps send me it so I can run java -version on it?

Our current binaries are printing out the java --version correctly.

13:55:02  openjdk version "11.0.8" 2020-07-14
13:55:02  OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.8+8-202006241234)
13:55:02  OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.8+8-202006241234, mixed mode)

@karianna is this ok to close? OP can always reopen if needs be 🙂
