Hi Thomas,
We are using batik api to generate images from svg content.
However, when we issue a multi threaded request to generate the
images, it is getting blocked in
org.apache.batik.util.SoftReferenceCache.requestImpl method ( According
to the stack trace)
Im attaching the stack trace with this email...
Please let me know what needs to be done.
Im using batik 1.5.1 on windows 2000 machine.
Thanks in advance,
Regards,
Vijay
