Downgrad JUnit version since JUnit 4 can only work with -target 1.5 or
higher class files.
Covered are Shell and Meterpreter stage, StreamForwarder, MemoryBuffer,
AESEncryption and Payload (Bind, Reverse, Spawn, AESPassword).
Check JavaPayload and Java Meterpreter against version incompatibilities
for Java 1.2, 1.3, 1.4, 1.5, and 1.6.
Note that webcam_audio_record is currently excluded from the checks, as it
uses Sun proprietary API for building the WAV file and is therefore
failing the build (and will most likely crash Meterpreter if run on a JVM
of version 1.4 or later that is not based on the Sun/Oracle JVM).
Possible workarounds (apart from either removing the module or changing it
to produce empty files when WAV creation is not supported) include
implementing the WAV file writer ourselves or providing raw PCM files
instead.
