which java JIRA is using

[Quan Wu]

for jira software 7.6.3 I am testing with Windowsserver 2012 and SQL2014,  I installed java on windows server , then install JIRA.

refer to the attached screenshot,  I wonder which java JIRA is using as today I just enable JMX monitoring, we did have some garbage collection issues.

Jira ships with a JRE in it and it looks like you're using it. Scroll up and you'll find a label called Java Version.

thank you ! can I use the java I installed instead ?  as that is the one up to date.  JIRA now showing on 1.8.0.102

should I re-install to indicate java directory or just change something in configuration ?

my java under c:\java\bin  version 1.8.0.151

by the way I do see issues related to performance on current site, reported to support line for followup.

Does depend on how you are running it, but if you set JAVA_HOME as an environment variable in one of the startup files, it will use whatever you put in there - in your example, you'd use c:\java  (Java knows that /bin below that is where to look for executables)

In most cases, you can set that in setenv.sh / setenv.bat, but for running it as a windows service, I think that is ignored and you need to do it in the service settings.

Thank you.  

C:\Atlassian\JIRA\jre\bin   is the one came with jira installation

c:\java\bin   is the one I installed

should I just go with C:\Atlassian\JIRA\jre\bin   as it is actually shown in system information 1.8.0.102  ?

but how to upgrade this java version inside jira ?  

is java upgrade coming with jira software version upgrade ? 

[Nic Brough [Adaptavist]]

It sounds to me like everything is working fine as it is, and there's no need for upgrades or changes.  If it's showing as running 1.8.0.102, and that's the version you want, great!

Java does get upgraded by Jira upgrades.

[Quan Wu]

thank you, so I don't need to worry about java upgrade at all then. 

What about restore data ?  if I restore data from A to B,  on B, any java related issue I should know ? 

[Nic Brough [Adaptavist]]

If they're the same version of Jira, no, you should be fine.  The exact version of Java is no that important either!
