SQuirreL won't launch

I'm trying to run SQuirreL on Ubuntu 18.04 but I'm not able to make it launch.

When I run

~/squirrel-sql-3.8.1/squirrel-sql.sh 

Nothing happens. I don't understand the sh script very well. I tried just running:

java -cp squirrel-sql.jar:~/squirrel/sql-3.8.1/lib* -splash:~/squirrel-sql-3.8.1/icons/splash.jpg net.sourceforge.squirrel_sql.client.Main --squirrel-home "~/squirrel-sql-3.8.1"

But it then says

java.lang.UnsatisfiedLinkError: no splashscreen in java.library.path at (ClassLoader.java:2541) at (Runtime.java:873) at (System.java:1857) at (SplashScreen.java:134) at (SplashScreen.java:132) at (Native Method) at (SplashScreen.java:131) at net.sourceforge.squirrel_sql.client.gui.SquirrelSplashScreen.<init>(SquirrelSplashScreen.java:37) at net.sourceforge.squirrel_sql.client.Application.startup(Application.java:219)

My Java version:

openjdk version 9-Ubuntu
OpenJDK Runtime Environment (build 9-Ubuntu+0-9b181-4)
OpenJDK 64-Bit Server VM (build 9-Ubuntu=0-9b181-4, mixed mode)

Any ideas?

Sorted out.

I upgraded to Java 10 via:

sudo apt-get install openjdk-11-jre openjdk-11-jdk

Now Java version reads:

openjdk version "10.0.1" 2018-04-17
OpenJDK Runtime Enviornment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server (buidl 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)

And now the application launches.

Below is the error i got when i tried to run squirrel-sql.sh. I had installed headless jdk hich as causing the issue.

Error :

sourabh@phoenix:~/squirrel-sql-4.1.0-standard$ ./squirrel-sql.sh
java.lang.UnsatisfiedLinkError: no splashscreen in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1860) at java.lang.Runtime.loadLibrary0(Runtime.java:871) at java.lang.System.loadLibrary(System.java:1124) ...........

Uninstall Headless Java JDK :

sourabh@phoenix:~/squirrel-sql-4.1.0-standard$ sudo apt-get remove openjdk-8-jre-headless 

Install Java JDL :

sourabh@phoenix:~/squirrel-sql-4.1.0-standard$ sudo apt-get install openjdk-8
