I have the following code (it doesn't require graphics environment to run):
(define-alias Font java.awt.Font)
(define-alias InputStream java.io.InputStream)
(define ClassLoader ::java.lang.ClassLoader
(java.lang.ClassLoader:getSystemClassLoader))
(define the-graphics-environment
::parameter[java.awt.GraphicsEnvironment]
(make-parameter
(invoke-static
java.awt.GraphicsEnvironment
'getLocalGraphicsEnvironment)))
(define (load-font path::String #!key
(size ::float 12.0))
(let* ((font-source ::InputStream
(ClassLoader:getResourceAsStream path))
(font ::Font (Font:createFont
Font:TRUETYPE_FONT
font-source))) (invoke
(the-graphics-environment) 'registerFont
font)
(font:deriveFont size)))
(define-constant Basic-Regular
(load-font "assets/Basic-Regular.otf" size: 20)
The Basic-Regular.orf file is present in the assets directory, located in
the same directory as the above file (that I called font-test.scm.
When I run the code with
$ kawa -f font-test.scm
it behaves well. But when I instead use
$ java -jar /path/to/kawa.jar -f font-test.scm
or
$ java -cp /path/to/kawa.jar kawa.repl -f font-test.scm
I get the following error:
java.io.IOException: Problem reading font data. at

kawa.repl.processArgs(repl.java:298) at
kawa.repl.main(repl.java:830)
I even went so far to modify the `which kawa` script by inserting "set -x"
in the first line following the she-bang:
+ KAWALIB=/data/data/com.termux/files/home/usr/share/kawa/lib/kawa.jar
+
CLASSPATH=/data/data/com.termux/files/home/usr/share/kawa/lib/kawa.jar:/data/data/com.termux/files/usr/share/java/android.jar:
+ export CLASSPATH
+ test -n
/data/data/com.termux/files/usr/opt/openjdk +
JAVA=/data/data/com.termux/files/usr/opt/openjdk/bin/java + JVM_FLAGS=
+ exec
/data/data/com.termux/files/usr/opt/openjdk/bin/java
-Dkawa.command.line=/data/data/com.termux/files/home/usr/bin/kawa -f
font-test.scm -Dkawa.command.pid=20316
-Dkawa.home=/data/data/com.termux/files/home/usr/share/kawa kawa.repl -f
font-test.scm
So - in orded to minimize the differences, I typed the following
incantation:
$ KAWALIB=/data/data/com.termux/files/home/usr/share/kawa/lib/kawa.jar
CLASSPATH=/data/data/com.termux/files/home/usr/share/kawa/lib/kawa.jar
/data/data/com.termux/files/usr/opt/openjdk/bin/java
-Dkawa.command.line="/data/data/com.termux/files/home/usr/bin/kawa -f
font-test.scm" -Dkawa.home=/data/data/com.termux/files/home/usr/share/kawa
kawa.repl -f font-test.scm
But that still doesn't work.
Does anyone know what could be the difference between these two runtime
environments?
(I checked, and they both report the same value of (current-path))

The latter is preferable, because it takes much less time. And the bundle also includes fonts. I'm also building an Android client, which virtually needs to use fonts from the bundle, because accessing the filesystem is problematic there.
