Can't execute java program on CentOS 7

Follow this guide to test JIRA performance:

https://github.com/atlassian/jira-performance-tests/blob/master/docs/tests/ON_PREMISE.md

Installed JAVA by:

$ sudo yum install java-11-openjdk-devel

Use this way got installed JAVA path:

$ update-alternatives --config java
java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java)

Set /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java to ~/.bash_profile as env variable:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java

Source file:

$ source ~/.bash_profile

Check JAVA_HOME:

$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java

From JIRA test path run test command:

$ cd jira-performance-tests/examples/btf-test
$ ./mvnw verify

Got error:

Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java/bin/java

Why?

    Hey you can do something like this to export the Java_Home

    export
    JAVA_HOME=”/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/”
    export PATH=$PATH:$JAVA_HOME/bin

    You should setup JAVA_HOME environment variable to: 

    /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java/bin

    To set JAVA_HOME, do one of the following:

    For Korn and bash shells, run the following commands:

    export JAVA_HOME=jdk-install-dir

export PATH=$JAVA_HOME/bin:$PATH

    For the bourne shell, run the following commands:

    JAVA_HOME=jdk-install-dir

export JAVA_HOME

PATH=$JAVA_HOME/bin:$PATH

export PATH

    For the C shell, run the following commands:

    setenv JAVA_HOME jdk-install-dir

setenv PATH $JAVA_HOME/bin:$PATH

export PATH=$JAVA_HOME/bin:$PATH

    Usually JAVA_HOME is given without /bin/java.
    I suggest changing the JAVA_HOME to /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64.
