Re: Trouble with Java completion

Hi David,

You're right, db-javap does deal with this :)  I could only replicate
your problem with db-javap turned off (i.e. not `require'd).  Once I
`require'd it it complained that generic projects don't have a
:classpath slot (which is of course true.)  Once I created a `java-root'
project, and dumped your code in it, it worked fine and gave me the
following options:

    clear        compute      
    computeIfAbsent computeIfPresent 
    containsKey  containsValue entrySet 
    equals       forEach      get 
    getOrDefault hashCode     isEmpty 
    keySet       merge        put 
    putAll       putIfAbsent  remove 
    replace      replaceAll   size 
    values

Are you using upstream or built in CEDET?

You can also turn on `global-semantic-decoration-mode' and your imports
will be decorated to indicate whether they have been:

 - Parsed (no highlighting)
 - Still need to be parsed (highlighted yellow on my machine)
 - None-file imports -- such as an import from a jar file (highlighted
   green on my machine)
 - Unrecognised imports (highlighted red on my machine)
 - (Your function tags will also be decorated in the buffer)

This ought to give you a good idea of whether cedet has figured out your
project setup.

To answer 1. and 2. I'm not familiar with the global versus local type
cache, but with any luck you wont have to be either :)

Kind regards,

Edward Steere
