Windows builds have two Eclipse signatures in the executables

[sxa]

What are you trying to do? Look at the signatures of the EXE/DLL files in the Windows builds

Expected behaviour: There is a single Eclipse signature on the files

Observed behaviour: There are two eclipse signatures on the files. Also the original MSFT signatures on the MSVC redistributable files are (correctly) preserved whereas in previous releases they were not

Any other comments: This was likely as a result of a change from Eclipse to use jsign instead of osslsigncode which was using a parameter to replace existing signatures.

Potential courses of action here (assuming the status quo is undesirable, which is my view):

1. Modify our pipelines to avoid the signing being invoked twice on the same file
2. Modify our scripting to check for the presence of an EF signature before invoking the signing
3. Adjust the tool to only replace EF signatures
4. Set the option on the new tool to replace existing signatures which is what the previous tool did (not a great solution since it would wipe the MSFT signature on the redist DLLs)
