I have created a JTextPane and loaded a html file. I am calling it's print method from within the run() method of a Runnable implementation. I am creating multiple threads using this Runnable implementation and starting them in a loop. All the print methods use the same print service and all are printing to different files.

When all the threads start calling the print method of JTextPane, lot of PrinterExceptions are thrown repeatedly. This is noticed only on WinXP and not reproducible on SolSparc10. This is reproducible on Mustang-b59d as well as b92. print() method is not supposed to throw any exception when called from multiple threads since we have claimed explicitly that it is thread-safe.

Here is the exception:
java.awt.print.PrinterException: A StartDocPrinter call was not issued.

I have attached a sample test. Execute the sample test as follows:
'java JTextCompPrintTest [no. of threads]' - I reproduced for 20-25 threads.
