PCH for java - is this a good idea?

[Martin Kahlert <martin dot kahlert at infineon dot com>]

Hi!

When gcj compiles java files, it has to make sure, that all the called
functions and classes are present with the correct signatures.
So i assume, it reads the file goodstuff.java if it comes around something like

goodstuff gs = new goodstuff();
gs.do_something();

So if i have a big number of files and goodstuff is some kind of a really
large support class, the compilation of every file has to read goodstuff.java
(if gcj is called from a makefile for example). This will last a long time.

So would it be a good idea, to build some kind of a compressed header file
for scanned .java files? Perhaps the PCH support of C/C++ (which seems to
be worked on) could be reused?

Thanks,
Martin.
