Is OGNL 2.7 compatible with JDK 1.4 ?

[Hugo Palma]

I'm asking because i'm getting this error running it:

Caused by: java.lang.RuntimeException: java.lang.RuntimeException:
java.lang.NoSuchMethodError: java.lang.Integer.valueOf(I)Ljava/lang/Integer;
   at ognl.ASTProperty.toSetSourceString(ASTProperty.java:548)

It seems that it's looking for an implementation of Integer.valueOf(Integer).
This kind of method call would only work in JDK 1.5.

Thanks,

Hugo
