I selected a target VM of 1.5. When I compile, the .man file contains this line:
Manifest-Version: -target 1.5
The manifest version should not contain -target and I am not sure that the version should be 1.5. When I generate the manifest using Ant, it puts this line in:
Manifest-Version: 1.0
Again use Build - Select Compiler - button Edit Configuration and correct this in the configuration at section [Build].
Please report also to IDM per email that the 2 configuration files in configs\Java Compiler\ contain the string "Created-By: UEStudio '05" which should be corrected / changed and that $(Target VM) is not correct for the Manifest-Version.
