This was a known issue, which was already fixed for 3.1.7. You can test it via a nightly snapshot from http://downloads.mysql.com/snapshots.php#connector-j

Caused by: java.lang.NullPointerException at com.mysql.jdbc.Messages.getString(Messages.java:70) at com.mysql.jdbc.Util.stackTraceToString(Util.java:118) at com.mysql.jdbc.Messages.<clinit>(Messages.java:50) ... 48 more I'm using Java 1.4.1_06, Tomcat 4.0. The Message.class.getClassLoader() method may return null. (Javadoc for getClassLoader() : Some implementations may use null to represent the bootstrap class loader.). The method getBundle() of ResourceBundle class must not have any null value for parameter. How to repeat: Use an implementation that return null when calling the method getClassLoader(). Suggested fix: static { try { ClassLoader cl = Messages.class.getClassLoader(); if (cl != null) { RESOURCE_BUNDLE = ResourceBundle.getBundle(BUNDLE_NAME, Locale.getDefault(), cl); } else { RESOURCE_BUNDLE = ResourceBundle.getBundle(BUNDLE_NAME, Locale.getDefault()); } } catch (Throwable t) { throw new RuntimeException("Can't load resource bundle due to underlying exception " + t.toString() + "\n\nStack Tace:\n\n" + Util.stackTraceToString(t)); } }
