Any hints are greatly > appreciated. That is strange. It is as if ecj is still compiling against a core class library that has a java.lang.reflect.Method which doesn't have the 1.5 getDefaultValue() method. Which shouldn't be possible since both -bootclasspath and -classpath are given and make sure the Method.java from the code you are compiling is being used. What version of ecj is this? Cheers, Mark
