Java 1.3.1 receives SEGV and dumps core in native code function
util_EuclidianDistance(), when java.awt.fonts is set to "".

The problem is strictly reproducible:

1. Testcase
-----------
Please find a complete testcase attached. The testcase consists of the
following files:
-rw-r--r-- 1 thomas sun 626 Aug 3 13:37 TestToolkit.java
-rw-r--r-- 1 thomas sun 142540 Aug 3 13:38 pja.jar
-rw-r--r-- 1 thomas sun 125725 Aug 3 09:50 doc.zip

"pja.jar" is 3rd party code and part of PJA 2.1 distribution of www.eteks.com.
It is used to build a virtual display on Unix servers without framebuffer.
"doc.zip" contains documentation for "pja.jar".
"TestToolkit.java" uses two of the classes, provided with "pja.jar".
