Subject: Issue with ManifestResourceTransformer and string length limit for
 main class

Hi,

I've added a maven-shade-plugin for the infamous Spring issues when creating
an uber jar.  Anyway in my ManifestResourceTransformer I specify my
executable class.  When I run mvn clean/install and then try to execute the
jar, I get a class not found issue.  When I expand the jar file that Maven
created and opened the Manifest.MF file, the class name for Main-Class was
placed in two lines.  This is what it looks like:

----------------------------------------------------------------------
Manifest-Version: 1.0
Build-Jdk: 1.7.0_17
Built-By: Dell
Created-By: Apache Maven
Main-Class: com.albeingters.buslogics.variablespeedcontroller.BusVSGat
e
Archiver-Version: Plexus Archiver
----------------------------------------------------------------------

Notice above that the "e" was put on the next line.  For testing purposes,
when I truncated the class name a couple of characters, everything seemed to
work fine.  So looks like Maven has some type of string length limit for the
main class.  Below is my pom configuration for that shader:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-shade-plugin</artifactId>
	<version>2.0</version>
	<executions>
		<execution>
			<phase>package</phase>
			<goals>
				<goal>shade</goal>
			</goals>
			<configuration>
				<minimizeJar>true</minimizeJar>
				<transformers>

					</transformer>
					<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
						<resource>META-INF/spring.schemas</resource>
					</transformer>
					<transformer

					</transformer>
					<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
						<manifestEntries>
							<Main-Class>${app.main.class}</Main-Class>
						</manifestEntries>
					</transformer>
				</transformers>
			</configuration>
		</execution>
	</executions>
</plugin> 


Using JDK 1.7_17 and Maven 3.0.5 command line
