Recently I started writing application using Java, NetRexx and BSF4ooRexx using the UCanAccess v5.0.1 Jar Archive. I discovered an issue that pertains specifically to ARM architecture based Linux Distros using the OpenJDK 8 Java Environmet and UCanAccess v 5.0.1.
I wrote a java program to list the Registered JDBC Drivers in my Open JDK8 $JAVA_HOME/jre/lib/ext directory. Java program is attached for your reference.
The result of that run yields the following Stack Trace Message ...
Drivers Registered with the DriverManager:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class net.ucanaccess.jdbc.UcanaccessDriver
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:348)
at java.sql.DriverManager.isDriverAllowed(DriverManager.java:556)
at java.sql.DriverManager.isDriverAllowed(DriverManager.java:548)
at java.sql.DriverManager.getDrivers(DriverManager.java:446)
at LstRegisteredJDBCDrivers.main(LstRegisteredJDBCDrivers.java:47)
This only occurs when I use the OpenJDK8 installation. It does not occure with the Oracle Java 8 JDK.
The issue occurs on both 32 and 64 bit Linux Architectures on the Raspberry Pi 4.
I realize that opting for the Oracle implementation of the Java JDK will resolve the issue, but I'd prefer to have a resolution for the OpenJDK implementaton as some of the Debian and Ubuntu Linux packages are dependent upon that installation.
Please let me know if I can provide any more details to help with the resolution of the issue.
