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,
