                 Key: LUCENE-1059
                 URL: https://issues.apache.org/jira/browse/LUCENE-1059
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Tzvika Barenholz
            Priority: Minor


IntelliJ IDEA found the following issues in the Lucense source code and tests:

1) explicit for loops where calls to System.arraycopy() should have been
2) calls to Boolean constructor (in stead of the appropriate static 
method/field)
3) instantiation of unnecessary Integer instances for toString, instead of 
calling the static one
4) String concatenation using + inside a call to StringBuffer.append(), in 
stead of chaining the append calls

all minor issues. patch is forthcoming.
