+ Due to a bug in openjdk 7 and 8, extra semicolons in import statements are
allowed. However, these extra semicolons can cause compilation failures with
other java
+ distributions since they are technically disallowed by the java spec.
These two regexes prevent extra semicolons in import statements. As an extra
side-effect they also
+ disallow certain usages of semicolons elsewhere in the body of a java
file. But we are okay with disallowing strange placement of semicolons in those
other cases.

Review comment:
Could you please consider using existing checks, since looks like a partial
case for this pattern: `code;;` is handled by already added `EmptyStatement`
check and more general case: `r = 5; int t;` may be handled by
[OneStatementPerLine](http://checkstyle.sourceforge.net/config_coding.html#OneStatementPerLine)
check.
