The Java ecosystem is being surveyed by Snyk in collaboration with Azul, aiming to create a comprehensive overview of the JVM 2021 landscape. The survey takes less than 3 minutes to complete and will be used to gather data on how developers use Java and the JVM ecosystem, as well as other available data points such as GitHub projects and Google searches. By participating, respondents can help the community share their data and contribute to a charity goal, with donations of $1000 for 2,000 responses and potentially up to $2000 if the target is exceeded.
