#error running igv **Error: A JNI error has occurred, please check your installation and try again

I already looked in previous questions since it appears that my issue is quite common. However I still cannot solve this problem.When I run the IGV program I got this error:

Error: A JNI error has occurred, please check your installation and try againException in thread "main" java.lang.UnsupportedClassVersionError: org/broad/igv/ui/Main has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0        at java.lang.ClassLoader.defineClass1(Native Method)        at java.lang.ClassLoader.defineClass(ClassLoader.java:763)        at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)        at java.net.URLClassLoader.defineClass(URLClassLoader.java:467)        at java.net.URLClassLoader.access$100(URLClassLoader.java:73)        at java.net.URLClassLoader$1.run(URLClassLoader.java:368)        at java.net.URLClassLoader$1.run(URLClassLoader.java:362)        at java.security.AccessController.doPrivileged(Native Method)        at java.net.URLClassLoader.findClass(URLClassLoader.java:361)        at java.lang.ClassLoader.loadClass(ClassLoader.java:424)        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)        at java.lang.ClassLoader.loadClass(ClassLoader.java:357)        at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:495)

I checked java versions:

java -versionopenjdk version "1.8.0_152-release"    OpenJDK Runtime Environment (build 1.8.0_152-release-1056-b12)    OpenJDK 64-Bit Server VM (build 25.152-b12, mixed mode)    javac -versionjavac 1.8.0_152-release    which java    /home/sche/anaconda2/bin/java

If I understand correctly I needed to install a uptdated version of java (e.g. 11):so I tried:

sudo apt update    sudo apt install openjdk-11-jdk 

however, still there is the old version

 java -versionopenjdk version "1.8.0_152-release"    OpenJDK Runtime Environment (build 1.8.0_152-release-1056-b12)     OpenJDK 64-Bit Server VM (build 25.152-b12, mixed mode)javac -version    javac 1.8.0_152-release    

I also tried manually with:

curl -O https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz    tar zxvf openjdk-11.0.2_linux-x64_bin.tar.gz    sudo mv jdk-11* /usr/local/    sudo vim /etc/profile.d/jdk.shexport JAVA_HOME=/usr/local/jdk-11.0.2export PATH=$PATH:$JAVA_HOME/bin

I really don't understand how to solve this issuethanks for your help
