    <p>Our java application is launchend via java web start (with glassfish 4.0). After updating to java 7u45, it doesn't work anymore. Here is the error message:</p> <pre><code>java.lang.NullPointerException at java.io.StringReader.&lt;init&gt;(Unknown Source) at org.glassfish.appclient.client.JWSAppClientContainerMain.insertMaskingLoader(JWSAppClientContainerMain.java:186) at org.glassfish.appclient.client.JWSAppClientContainerMain.main(JWSAppClientContainerMain.java:132) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.javaws.Launcher.executeApplication(Unknown Source) at com.sun.javaws.Launcher.executeMainClass(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source) </code></pre> <p>This happens right after the download finished. After a quick look into the GF source file, it seems that the property <code>loader.config</code> is not defined as the second line throws the NPE:</p> <pre><code>final String loaderConfig = System.getProperty("loader.config"); StringReader sr = new StringReader(loaderConfig); </code></pre> <p><strong>EDIT</strong> The above two code lines where the NPE happens is Glassfish code, from the Class <code>JWSAppClientContainerMain</code> in the jar <code>gf-client-module.jar</code>. It worked until java update 45.</p>

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.

SQuiL has stopped working due to an internal error.

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