[rules-dev] Bug report - a lucky catch if I ever saw one

[Wolfgang Laun]

Still there.

Perhaps a trim() in here?

public class JavaModifyBlockDescr implements JavaBlockDescr {
    private int start;
    private int end;
    private String modifyExpression;
    private List<String> expressions;

    public JavaModifyBlockDescr( String modifyExpression ) {
        this.modifyExpression = modifyExpression*.trim()*;
        this.expressions = new ArrayList<String>();
    }
