Xerces doesn't close the stream when reading

[Tobbi <to...@systinet.com>]

   Hi,
I've found a problem on WebLogic server. I port my application under server and trying to parse files stored directly in .jar file. Using Xerces 2.0 JAXP interfaces I get sometimes an exception that resource wasn't found.

1) my main class is in my.jar
2) in my.jar is also com/my/resource.xml
3) using JAXP

... create DocumentBuilderFactory
... create DocumentBuilder
... URL url = this.getClass().getClassLoader().getResource("com/my/resource.xml")
... documentBuilder.parse(url.externalForm());

notes: factory is static, common for each call
          builder is created for each call
          in the second or third parsing I get an exception from parse() method that resource is not available
          exception comes from URL.openStream() method inside DOMParser

I've found that parse() function CREATES a stream but doesn't CLOSE it!
It seems like sometimes garbage collector erases URL and stream from memory and all is ok, but sometimes exception occurs.

   Is this a bug or I've missed some my mistake?

   Best regards, Tomas Bouda
