Example: class A { private Collection<I> a[]; ^ } Using content assist to get proposals for Collection type argument will throw the following exception: java.lang.NullPointerException at org.eclipse.jdt.internal.codeassist.CompletionEngine.isValidParent(CompletionEngine.java:6334) at org.eclipse.jdt.internal.codeassist.CompletionEngine.complete(CompletionEngine.java:733) at org.eclipse.jdt.internal.codeassist.CompletionEngine.complete(CompletionEngine.java:1766) at org.eclipse.jdt.internal.core.Openable.codeComplete(Openable.java:123) at org.eclipse.jdt.internal.core.CompilationUnit.codeComplete(CompilationUnit.java:313) Note that it works perfectly using the other array declaration syntax: class A { private Collection<I>[] a; ^ } It also works, regardless of the syntax used, when the declaration is local to a method: public void method() { Collection<I> a[]; ^ Collection<I>[] b; ^ }
