    <p>I restrated my program and it just blew up. All I changed in it were some String.format() returns and reverting those changes did not make this error go away. When I research the error it appears to be related to Maven? But im using ANT to build the project.</p> <pre><code>Exception in thread "Thread-2" java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file InHouseLeague/Workers/BotListener at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:791) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at org.schwering.irc.moep.MoepIRC.run(MoepIRC.java:831) at java.lang.Thread.run(Thread.java:722) </code></pre> <p>The code its referenceing (I havent touched in weeks) </p> <pre><code>public void run() { updateTab(Util.CONSOLEWINDOWINDEX, "# Trying to connect to "+ host, serverColor); enableConnectMenuItem(false); username = username.toLowerCase(); if (!useSSL) { conn = new BotConnection(host, portMin, portMax, password, nickname, username, realname); } else { BotSSLConnection sslconn = new BotSSLConnection(host, portMin, portMax, password, nickname, username, realname); if (!autoAcceptSSLCerts) sslconn.addTrustManager(new AskTrustManager()); conn = sslconn; } conn.addIRCEventListener(new BotListener(this)); //ERROR POINTS TO HERE conn.setColors(true); conn.setPong(false); conn.setDaemon(true); try { conn.connect(); this.isConnected = conn.isConnected(); } catch (Exception exc) { String reason = ""; if (exc.getMessage() != null) { reason = ": "+ exc.getMessage(); } updateTab(Util.CONSOLEWINDOWINDEX, "# Couldn't connect"+ reason, serverColor); enableConnectMenuItem(true); exc.printStackTrace(); this.isConnected = false; } } </code></pre> <p>The changes I made before this happened:</p> <p>From:</p> <pre><code> @Override public String toString() { String returnStr = String.format("%s(ELO: %d):", getTeamName(), teamELO); for (IPlayer player : roster) { returnStr = String.format("%s %s", returnStr, player.getUserName()); } return returnStr; } </code></pre> <p>To</p> <pre><code> public String toString() { String returnStr = String.format("%s[%d]:", getTeamName(), teamELO); for (IPlayer player : roster) { returnStr = String.format("%s %s;", returnStr, player.getUserName()); } return returnStr; } </code></pre>

    2. COI dont even know where to begin with showing the code. As I mentioned the change was so minor. It was literally reformatting a string.

    3. COWhat kind of app is this? Is in a web app hosted in some kind of container? A lot of the google results say that it's some weird dependency issue. What's your class path look like? What's the ant target look like?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
