testDeserializationOfNotWhiteListedClassThrowsError sometimes fails

[vladak]

The ConfigurationTest.testDeserializationOfNotWhiteListedClassThrowsError test sometimes fails on Windows, specifically with the 2 parameter:

Looks like the class loader actually allows the configuration to pass and the Configuration deserialization then fails with IOException.

The 2nd string contains curl invocation:

opengrok/opengrok-indexer/src/test/java/org/opengrok/indexer/configuration/ConfigurationTest.java

Line 201 in f8a4c2e

" <string>/usr/bin/curl https://oracle.com</string>\n" +

I have seen this on Linux build as well.

Once the configuration is converted to some other serialization scheme, preferably one that does not allow code injection (#2329), this test can be removed, however my feeling is that this will take some time.
