PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• If contributing template-only or documentation-only changes which will change sample output, build the project beforehand.
• Run the shell script ./bin/generate-samples.shto update all Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master. These must match the expectations made by your contribution. You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*. For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

Can you strip any leading and trailing / and / from the regex pattern before it is passed into rxgen? That will solve this problem.

Thank you for your PR! This looks great!

Hello @spacether and @code-lucidal58.

I've got a feeling that the fix is incorrect:

I think that instead of:

while (pattern.startsWith("/")) pattern = pattern.substring(0, pattern.length()-1);
while (pattern.endsWith("/")) pattern = pattern.substring(1);

there should be:

while (pattern.endsWith("/")) pattern = pattern.substring(0, pattern.length()-1);
while (pattern.startsWith("/")) pattern = pattern.substring(1);

i.e. when ends with slash - truncate from end, when starts with slash - truncate from start.

Pardon me for this silly mistake. Here is the edit: #8219
