http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13586 fop will not work on linux alpha because jre is broken (workarround included) Summary: fop will not work on linux alpha because jre is broken (workarround included) Product: Fop Version: 0.20.4 Platform: Alpha OS/Version: Linux Status: NEW Severity: Blocker Priority: Other Component: pdf renderer AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The jre-1.3.1 for linux-alpha has an ugly floating point bug. The java-engine raises SIGFPE when comparing a value with NaN at least under some conditions. Well, this is not a Fop bug, but I suggest to change the current PDF renderer to work arround the problem. I don't know when Digital/Compaq/HP (or the AXP technology owner of the day) will fix this or release a new jre: PDFRenderer.java: on axp, I use float currentLetterSpacing = (float) 99999.99; instead of: float currentLetterSpacing = Float.NaN; to avoid crashes right here: if (letterspacing != this.currentLetterSpacing) { ... } to make the thing work on linux axp. For everlasting amusement, I attach a backtrace (debug on, optimizer off): + exec /usr/opt/axp-fop/jre1.3.1/bin/alpha/native_threads/java -Xrs -cp /opt/axp-fop/fop-0.20.4/lib/avalon-framework-cvs-20020315.jar:/opt/axp-fop/fop-0.20.4/lib/xml-apis.jar:/opt/axp-fop/fop-0.20.4/lib/xercesImpl-2.0.1.jar:/opt/axp-fop/fop-0.20.4/lib/xalan-2.3.1.jar:/opt/axp-fop/fop-0.20.4/lib/batik.jar:/opt/axp-fop/fop-0.20.4/build/fop.jar org.apache.fop.apps.Fop fop_bild.fo fop_bild.ps Warning: JIT compiler "none" not found.
