java - NoClassDefFoundError sun/io/ByteToCharConverter with InterBase JDBC driver -


with interclient 7.5.1 , 8.1.5, creation of new jdbc connection in java 8 fails with

java.lang.noclassdeffounderror: sun/io/bytetocharconverter

this class seems referenced or used interclient jdbc library. error not occur java 7. there way work around error?

this code reproduces problem on java 8:

package com.example.so25365952;  import java.sql.drivermanager; import java.sql.sqlexception; import java.util.logging.level; import java.util.logging.logger;  public class main {     interbase.interclient.connection conn;       public static void main(string[] args) {         try {             class.forname("interbase.interclient.driver");                        drivermanager.getconnection("jdbc:interbase://localhost/data/mydb.gdb", "sysdba", "password123");                    } catch (classnotfoundexception | sqlexception ex) {             logger.getlogger(main.class.getname()).log(level.severe, null, ex);         }     } }

output:

exception in thread "main" java.lang.noclassdeffounderror: sun/io/bytetocharconverter @ interbase.interclient.connection.connect(unknown source) @ interbase.interclient.connection.(unknown source) @ interbase.interclient.driver.connect(unknown source) @ java.sql.drivermanager.getconnection(drivermanager.java:664) @ java.sql.drivermanager.getconnection(drivermanager.java:247) @ com.example.so25365952.main.main(main.java:14) caused by: java.lang.classnotfoundexception: sun.io.bytetocharconverter @ java.net.urlclassloader$1.run(urlclassloader.java:372) @ java.net.urlclassloader$1.run(urlclassloader.java:361) @ java.security.accesscontroller.doprivileged(native method) @ java.net.urlclassloader.findclass(urlclassloader.java:360) @ java.lang.classloader.loadclass(classloader.java:424) @ sun.misc.launcher$appclassloader.loadclass(launcher.java:308) @ java.lang.classloader.loadclass(classloader.java:357) ... 6 more

the sun.* , sunw.* packages internal , should not used reason. seems @ interclient screwed up. i'd advise contact them bug report, they'll know fix future releases.

if can't wait future release, , willing break licences (which don't recommend of course). may able create own sun.io.bytetocharconverter copying code here, , adding bootstrap classpath -xbootclasspath, last resort.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
