Heikki Linnakangas commented on DERBY-73:
-----------------------------------------

JavaCC version 3.2 changes the variable name from "enum" to "e". It's The javacc.jar in tools/java should be upgraded.

>      Project: Derby

> Compilation fails when using JDK1.5 due to
> 1) no specification of language level
> 2) use of "enum" as identifier
> The language issue results in the use of the new StringBuilder class for string concatenation resulting in code that will not run on earlier JVMs.
> Dropping the langauge level will allow it to compile but warnings are generated due to the use of "enum" as an identifier; with 1.5 this becomes a reserved word
