      Description

      In an effort to use pstoedit (2.5) filter front end to ghostscript to convert postscript files to java applets, found a combination that crashes Java's virtual machine all browsers with a SIGSEGV segment violation. I've attached the PostScript file, the Java code generated, and the HTML file invoking it. To see this happen, try accessing the following URL through either Netscape 3.0 from softdist or any of the HotJava builds.

      SPARC appletviewer is crashed with the following diagnostics:
