When building a job with a git branch specifier that ends with a wildcard (ie origin/feature/* or origin/feature*) jenkins never releases its hold on .git/object/pack/.pack files. This causes the next build to not be able to wipe the workspace. This is not a problem if the branch specifier does not end with a wildcard.

The *.pack file cannot be deleted until the javaw.exe process (JNLP connection to jenkins) is killed.

The only way I have been able to get by is to not wipe the workspace before builds.

This is the stack trace that this causes...
