Looks like the StringCoding class is not loaded/initialized in e.g. a HelloWorld on AIX, compare Linux vs. AIX : /linuxx86_64/images/jdk/bin/java -Xlog:class* Hello | grep StringCoding [0.049s][info][class,load ] java.lang.StringCoding source: shared objects file [0.049s][info][class,init ] 268 Initializing 'java/lang/StringCoding'(no method) (0x0000000800074450) /rs6000_64/images/jdk/bin/java -Xlog:class* Hello | grep StringCoding <nothing> So probably some other class than StringCoding should be used in the test.
