Summary: recent builds of drjava crash on startup
Initial Comment:
On my home machine (a Dell GX 100 running Linux 7.1),
the two most recent builds of drjava
(drjava-20020108-0956.jar and drjava-20020116-1013.jar)
crash most of the time on startup with the following
traceback (after printing out a number of
"font .. not found" messages). I normally run Sun
JDK 1.4 beta, but I have seen this behavior under
JDK 1.3.1 as well. The bug always generates the
same trackback, which follows:
...
Font specified in font.properties not found [--standard
symbols
l-medium-r-normal--*-%d-*-*-p-*-urw-fontspecific]
java.lang.NullPointerException: null

By the way, the JVM hangs after printing the preceding
line. It does not terminate.
The crashing does not appear to be random. For
both build, it appears to crash every time that
I start it using JDK 1.4 beta from my home directory,
e.g.
java -jar drjava/drjava-20020116-1013.jar
but it usually (always?) succeeds when I cd
to my drjava directory and type
java -jar drjava-20020116-1013.jar. I just tried
the same tests under JDK 1.3.1 and encountered
the same behavior.
