Note that you can run the test by adding the following line to the
build.properties file:
test.entry=org.apache.coyote.http11.filters.TesterFlushableGZIPOutputStream

Just for reference:
If I run the test through Ant it fails in an odd way:

[[[
Testsuite: org.apache.coyote.http11.filters.TesterFlushableGZIPOutputStream
Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0,031 sec

Testcase: testBug52121 took 0,016 sec
    Caused an ERROR
null
java.lang.NullPointerException
    at org.apache.catalina.util.IOTools.flow(IOTools.java:74)
    at org.apache.catalina.util.IOTools.flow(IOTools.java:85)
    at
org.apache.coyote.http11.filters.TesterFlushableGZIPOutputStream.testBug52121(TesterFlushableGZIPOutputStream.java:47)
]]]

I cannot explain this NPE.

If I run it as JUnit test from with Eclipse IDE I get the IO error:
