JAVA_HOME is null when running test via UI

[dipak-pawar]

Description

Env variable JAVA_HOME is null when running tests from UI. Whereas it's working as per expectation when running maven build from terminal.

Reproduction Steps:

• Open project https://github.com/dipak-pawar/che_java_home_reproducer in che
• Run Junit Test from UI.

@dipak-pawar what stack do you use?

[dipak-pawar]

@eivantsov I have used vert.x, java-centos. Getting same issue for both the stack.

Is JAVA_HOME set as env there? Does java.home work?

[dipak-pawar]

I can echo $JAVA_HOME on che terminal. But couldn't get it in java program.

whereas I can get System.getProperty("java.home") to respective jre directory.

@eivantsov thanks, because it fails for me ;-)

[dipak-pawar]

Same for me - not available in unit tests

I think you can use System.getProperty("java.home"); instead.
We will close this issue as normal behavior because in you case tests run in separate jvm which doesn't have JAVA_HOME properties
