Custom import order not behaving as expected

[Björn Lindahl]

Hi, I'm experiencing issues with getting CustomImportOrder working properly. I have theese imports

```

import se.pkg1.pkgA.pkgX.SomeClass1 // #1

import se.pkg1.pkgA.pkgX.SomeClass2 // #2

import se.pkg1.pkgB.pkgNotX.SomeClassX // #3

```

My CustomImportOrder definition looks like this:

```<module name="CustomImportOrder">
            <property name="severity" value="error"/>
            <property name="customImportOrderRules"                      value="STANDARD_JAVA_PACKAGE###THIRD_PARTY_PACKAGE###SPECIAL_IMPORTS###SAME_PACKAGE(3)###STATIC"/>
            <property name="standardPackageRegExp" value="java|javax|jakarta"/>
            <property name="thirdPartyPackageRegExp" value=" se.pkg1.pkgA"/>
            <property name="specialImportsRegExp" value="se.pkg1"/>
            <property name="sortImportsInGroupAlphabetically" value="true"/>
            <property name="separateLineBetweenGroups" value="true"/>

        </module> 

My interpretation and also how the IntelliJ Checkstyle plugin order the imports is that packages in se.pkg1.pkgA falls within THIRD_PARTY_PACKAGE and so #1 and #2 above is grouped together. 

#3 on the other hand falls within SPECIAL_IMPORTS and should be grouped separate, below THIRD_PARTY_PACKAGE. The problem is though that if I import checkstyle config in IntelliJ java imports it seem to work as expected but when I run the 

maven-checkstyle-plugin it think all three imports should belong to the same group as this:

```

import se.pkg1.pkgB.pkgNotX.SomeClassX // #3

import se.pkg1.pkgA.pkgX.SomeClass1 // #1

import se.pkg1.pkgA.pkgX.SomeClass2 // #2

```

Which is the correct order you'd say?

Thanks!

Sorry, I messed up the code formatting. Maybe some moderator can fix it making it more readable.
