Description

The error I experience in around every 4th build is

-------------------------------------------------------------------------------
Test set: org.apache.jackrabbit.vault.fs.impl.io.CompressionUtilTest
-------------------------------------------------------------------------------
Tests run: 3, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.012 s <<< FAILURE! - in org.apache.jackrabbit.vault.fs.impl.io.CompressionUtilTest
testCompressibilityEstimation(org.apache.jackrabbit.vault.fs.impl.io.CompressionUtilTest)  Time elapsed: 0.007 s  <<< FAILURE!
junit.framework.AssertionFailedError
	at org.apache.jackrabbit.vault.fs.impl.io.CompressionUtilTest.testCompressibilityEstimation(CompressionUtilTest.java:58)

This is due to the fact that the test relies on java.util.Random to generate a byte array. Sometimes this leads to byte arrays which are actually compressible.
