A DESCRIPTION OF THE PROBLEM :
Certain particular manifests, if written to an output stream
using JDK 1.3, are written incorrectly - the format is
invalid and cannot be read again.

Seems to be fixed in JDK 1.4, but I see no filed bug about
it, and no 1.3.1_0x update release seems to mention it.

Only observed on this manifest - many others are written
just fine.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run attached program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected (from 1.4):

---%<---
Manifest-Version: 1.0
OpenIDE-Module-Specification-Version: 2.13
OpenIDE-Module-Layer:
org/netbeans/modules/apisupport/ant/mf-layer.xml
OpenIDE-Module-Localizing-Bundle:

 TemplateNames.properties
Created-By: Apache Ant 1.5.1
OpenIDE-Module-Module-Dependencies:

OpenIDE-Module: org.netbeans.modules.apisupport.ant
OpenIDE-Module-Implementation-Version: 200302030958
OpenIDE-Module-IDE-Dependencies: IDE/1 > 3.14

Equal: true
---%<---

Actual (from 1.3): throws exception after printing

---%<---
Manifest-Version: 1.0
OpenIDE-Module-Layer:
org/netbeans/modules/apisupport/ant/mf-layer.xml
OpenIDE-Module-Implementation-Version: 200302030958

 TemplateNames.properties

---%<---

Note extra "\n " at end of
OpenIDE-Module-Module-Dependencies attr line.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.io.IOException: invalid manifest format
at java.util.jar.Manifest.read(Manifest.java:180)
at java.util.jar.Manifest.<init>(Manifest.java:51)
at ManifestWriteTest.main(ManifestWriteTest.java:12)

The exception is expected - the format is indeed invalid.

REPRODUCIBILITY :
This bug can be reproduced always.
