    <p>I have the following interface:</p> <pre><code>public interface Translator { public &lt;T, F&gt; T translate(F from, T to, Class&lt;T&gt; clazz); } </code></pre> <p>and the following implementation:</p> <pre><code>class TranslatorImpl implements Translator { @Override public &lt;T, F&gt; T translate(F from, T to, Class&lt;T&gt; clazz) { //some code } } </code></pre> <p>But for the <code>translate()</code> method in the <code>TranslatorImpl</code> class, Eclipse complains as follows:</p> <blockquote> <p>Name clash: The method translate(F, T, Class) of type TranslatorImpl has the same erasure as translate(F, T, Class) of type Translator but does not override it</p> </blockquote> <p>Update: When I do a Maven build it builds properly. I use JDK 1.6 update 31. The JDK compliance level in Eclipse is 1.6</p> <p>How do I overcome this?</p> <p>Update 2:</p> <p>Compliance level settings: <img src="https://i.stack.imgur.com/MCIec.png" alt="enter image description here"></p> <p>Installed JRE: <img src="https://i.stack.imgur.com/zDiMW.png" alt="enter image description here"></p> <p>Update 3: Contents of my <code>.classpath</code> file:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;classpath&gt; &lt;classpathentry kind="src" output="target/classes" path="src/main/java"/&gt; &lt;classpathentry kind="src" output="target/test-classes" path="src/test/java"/&gt; &lt;classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/&gt; &lt;classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"/&gt; &lt;classpathentry combineaccessrules="false" kind="src" path="/dbmodel"/&gt; &lt;classpathentry combineaccessrules="false" kind="src" path="/uimodel"/&gt; &lt;classpathentry combineaccessrules="false" kind="src" path="/common"/&gt; &lt;classpathentry kind="var" path="MAXIMUS_DEV_DIR/resources/dependencies/java/log4j/log4j-1.2.16/log4j-1.2.16.jar"/&gt; &lt;classpathentry kind="output" path="target/classes"/&gt; &lt;/classpath&gt; </code></pre> <p>Update 4: project specific compiler compliance level settings: <img src="https://i.stack.imgur.com/QuX8f.png" alt="enter image description here"></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.

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