There's a smidge more information from "java test": 
C:\Users\Shai\Documents\HadToDL\PLJava-0.04>java test
PLJava - Native code library failed to load. See the chapter on Dynami
+c Linking
Problems in the SWIG Java documentation for help.
java.lang.UnsatisfiedLinkError: perl5.PLJavaJNI.PLJava_start()I

[download]

Don't know if it helps all that much though. That perl5.PLJavaJNI.PLJava_start() is the culprit suggests that the problem is happening when Java tries to use the native function from the C component -- it fails at the border. Of the possible causes for this exception that the SWIG documentation lists, "unresolved symbols in the compiled C/C++ code" and "ensure that you are using the correct C/C++ compiler and linker combination and options for successful native library loading." would be the leading candidates -- the error occurs after the .dll loading happens. "java -verbose:jni test" doesn't say anything about unresolved symbols, though, and I can't seem to find anything about compiler-linker combinations in that SWIG Wiki... hmm.
