Examples of org.eclipse.jgit.api.errors.JGitInternalException

org.eclipse.jgit.api.errors.JGitInternalException
Exception thrown when during command execution a low-level exception from the JGit library is thrown. Also when certain low-level error situations are reported by JGit through return codes this Exception will be thrown.
During command execution a lot of exceptions may be thrown. Some of them represent error situations which can be handled specifically by the caller of the command. But a lot of exceptions are so low-level that is is unlikely that the caller of the command can handle them effectively. The huge number of these low-level exceptions which are thrown by the commands lead to a complicated and wide interface of the commands. Callers of the API have to deal with a lot of exceptions they don't understand.
To overcome this situation this class was introduced. Commands will wrap all exceptions they declare as low-level in their context into an instance of this class. Callers of the commands have to deal with one type of low-level exceptions. Callers will always get access to the original exception (if available) by calling {@code #getCause()}.
