Unit Tests: OSX/Java7 w/o 32bit tests ; Reliable Test1p*JavaEmitter JNI binding initialization

- OSX/Java7 w/o 32bit tests

  OSX/Java7 has no 32bit JVM, disable d32 tests for such, using property 'use.macosx32'

- Reliable Test1p*JavaEmitter JNI binding initialization

  Load libs and init JNI binding statically w/ @BeforeClass,
  since OSX/Java7 for some reason gets confused (?) w/ init sequence.
  This is no issue for JOGL etc .. as far we have observed.
