Agent capability set in startup with a space in the name not recognized by job requirement.

Summary

When defining a capability in the file bamboo-capabilities.properties, with a space on the name, the agent won't be shown as available after setting that capability as requirement.

Environment

Bamboo with Remote agents. Non-OS specific.

Steps to Reproduce

1. Create a file called bamboo-capabilities.properties under <bamboo-agent>/bin. For this test, it was populated ini this way:

   system.builder.msbuild.MSBuild\ v2.0\ (32bit)=C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v2.0\ (64bit)=C:\\Windows\\Microsoft.NET\\Framework64\\v2.0.50727\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v3.5\ (32bit)=C:\\Windows\\Microsoft.NET\\Framework\\v3.5\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v3.5\ (64bit)=C:\\Windows\\Microsoft.NET\\Framework64\\v3.5\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v4.0\ (32bit)=C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v4.0\ (64bit)=C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v12.0\ (32bit)=C:\\Program Files (x86)\\MSBuild\\12.0\\bin\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v12.0\ (64bit)=C:\\Program Files (x86)\\MSBuild\\12.0\\bin\\amd64\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v14.0\ (32bit)=C:\\Program Files (x86)\\MSBuild\\14.0\\bin\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v14.0\ (64bit)=C:\\Program Files (x86)\\MSBuild\\14.0\\bin\\amd64\\MSBuild.exe
   system.builder.msbuild.MSBuild\ v15.0\ (32bit)=C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Professional\\MSBuild\\15.0\\Bin\\msbuild.exe
   system.builder.msbuild.MSBuild\ v15.0\ (64bit)=C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Professional\\MSBuild\\15.0\\Bin\\amd64\\msbuild.exe
   

1. Start the agent.
2. In Bamboo, if needed approve the agent and check that the capabilities are listed:
3. 
4. Navigate to a plan and a job, section "Requirements".
5. Add one of the capabilities.

Expected Results

The agent should be shown as an option.

Actual Results

Bamboo says no agents can build that job.

Notes

No errors in agent/server logs

Workaround

Manually add the capabilites through the UI
