I'm using the JFlex tool bundled with IDEA #7051 and it's generating source that won't compile. Specifically, it's generating the following line in the lexer's reset method:
zzBufferArray = com.intellij.util.text.CharArrayUtil.fromSequenceWithoutCopying(buffer);
IDEA complains (as does the compiler) that the fromSequenceWithoutCopying method does not exist.
I'm executing JFlex using a java task in an ant build script with the following args: --nobak --charat --skel idea-jflex.skeleton -d /my/output/dir /my/grammar.flex
