I was typing in the Java editor when code completion stopped working, instead 
it gave a status bar message "No completions available".
It still worked in other files and it seems it is related to what I was 
entering (although no errors were shown).

Code completion stopped for variables, methods and types, so the following did 
nothing (~ indicates Ctrl + SPACE pressed)

Str~

String name;
nam~
name.~

It seems to be related to generics.  In the following code, the only difference 
between working and non-working code are the lines with generics:

The following code gives "No completions available" when edited

public class TestCompletion
{
	public static void unpack(String project)
	{
		ZipFile file;
		try
		{
			file = new ZipFile(project);
			Enumeration<ZipEntry> entries = (Enumeration<ZipEntry>)
file.entries();  // >>>> generics here
			while (entries.hasMoreElements())
			{
				ZipEntry entry = entries.nextElement();  // 
>>>> no cast here
				String name = entry.getName();
			}
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}
}

//----------------------------------------------------------------------------
and for this version code completion works:

public class TestCompletion
{
	public static void unpack(String project)
	{
		ZipFile file;
		try
		{
			file = new ZipFile(project);
			Enumeration entries = file.entries();  // >>>> no 
generics here
			while (entries.hasMoreElements())
			{
				ZipEntry entry = (ZipEntry)entries.nextElement
();  // >>>> cast here
				String name = entry.getName();
			}
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}
}
//-----------------------------------------------------------------------------

It is also something about the cast, because if I replace the Zip classes with 
Jar classes and remove the cast on the entries, code completion keeps working.

Good luck.
