JVM hangs when calling FOP on stylesheet with SVG
Summary: JVM hangs when calling FOP on stylesheet with SVG
Product: Fop
Version: 0.20.1
Platform: HP
OS/Version: HP-UX
Status: NEW
Severity: Critical
Priority: Other
Component: svg
AssignedTo: fop-dev@xml.apache.org
ReportedBy: sillen@init.se
Hello, JVM hangs when called on a stylesheet with SVG. We can't use System.exit()
as in the CommandLineStarter because we're using FOP from within a application
server. The SIGKILL shows that the thread is blocking on
org.apache.batik.util.SoftReferenceCache line 186, which is doing a remove() on
a java.lang.ref.ReferenceQueue. I don't know if this is a JVM bug (we have tested
this on HP and Linux with different JVM's) or if this could be "hacked" around
in the sources.
