Hello Phil.
I appreciate your reply.
I put problem analysis information in JDK-8221741 [1].
The issue is AIX's Xserver was frozen about 25 secs on my local AIX box.
According to my problem analysis,
In this case, Java tried to load large 11 X11 bitmap fonts via
XLoadQueryFont() on Xlib.
The situation can emulate by "xlsfonts -ll" command, like:
$ time xlsfonts -ll -fn
"-monotype-sansmonowt-medium-r-normal--*-80-72-72-*-*-ucs2.cjk_japan-0"
...
real 0m2.07s
user 0m0.00s
sys 0m0.00s
One of solution is, Unix's fontconfig.properties can support
TrueType/Type1 font name format. [2]
Anyway,
I don't know the reason why X11 bitmap font is required for logical
font.
(I don't know how to use X11 bitmap font for physical font.
I could not see X11 bitmap font name via
GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames().)
I just want to fix Xserver frozen issue.
I appreciate your advice.
(Other solutions are welcome)

Could you review the fix ?

I'd like to obtain a sponsor for this issue.
On AIX platform, fontconfig.properties file is used to pick up proper
fonts.
TrueType font settings are written by XLFD format on
fontconfig.properties file.
On current implementation, Java tries to load X11 bitmap fonts even if
these are not used.
I think you need to clarify what you mean here.
I'd like you to provide a step by step analysis of what happens and
what the effect of your proposed change is on AIX *AND* what it might
mean for other X11 platforms, as I don't have time to reverse engineer
the
reasons for the odd-looking change.
It looks like a hack to short-circuit support your syntax.
Right now I am saying no to this.
This font load work is almost name as "xlsfonts -ll".
It spends many CPU time and memories.
Just font name format should be supported.
Not clear enough for me.

To SAP representative,
I have a question about copyright year on
make/data/fontconfig/aix.fontconfig.properties.
Please let me know how I should write down copyright year.
