Hi, Here is my suggested fix for the FilterOuputStream issue in JDK-8054565. I have been running this fix in my applications for several weeks (by adding it to the bootstrap classpath) and it solves my issue. The fix creates a new member field to remember whether close has already been called on the stream, and if so, close() does nothing.
Attached is the output from hg diff -g This is my first attempt at a patch for OpenJDK, so please let me know if I need to change anything. Thanks, Nathan
