Java is no doubt a powerful and robust programming language with a huge ecosystem. But, it is not ideal for startups. In fact, it may not even be all that good for larger projects either.
- Can be a continuous and steep learning curve especially hindered by the 6 monthly release cycles
- Verbose syntax
- Often a pain with longer development cycles
- Heavier runtime environment
- Again those 6 monthly releases are frustrating and annoying
- Higher resource consumption
- Huge outlay for cloud development
- Less flexible ecosystem
- Initial setup and configuration time
- Build and deployment complexity
- Potential for major performance bottlenecks
- Licensing costs
- Time and effort in manhours
- Lots of unnecessary boilerplate code
- Compilation times
- Strict typing can be a headache
- Slow development cycles
- Lots of third-party libraries that can lead to security vulnerabilities with larger attack surfaces
- Auditing complexity due to larger codebases
- Leads to dependency hell from transitive dependencies, to version conflicts, to outdated dependencies that can cause build failures and runtime errors
