[Unable to launch IDE] Error message: ODS supports Java version 1.8.0_60 and newer

[First-time user here]

I've recently downloaded the tarfile for ODS 12.6 (on CentOS 6.6) and tried to launch the IDE by running "devstudio" but I got the error message

Developer Studio supports Java version 1.8.0_60 and newer and looks for a valid Java installation in the following order:

1) Location specified with --jdkhome command line option

2) On Mac OS X at location specified by /usr/libexec/java_home --version 1.8.0+ --failfast

3) On Mac OS X at /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/bin

4) In the PATH environment variable

5) At /usr/jdk/latest/bin

6) On Linux at /usr/java/latest/bin

7) At /usr/java/bin

8) At /usr/bin

So I installed Oracle Java SE Development Kit 11 (the latest) but I'm still getting the above error. (I'm not a Java developer. I'm looking to use ODS for C++ development)
