elharo opened a new issue, #170:
URL: https://github.com/apache/maven-toolchains-plugin/issues/170
## Summary
launches a subprocess and calls without a timeout. A hung or slow JVM
process will block Maven indefinitely.
## Location
https://github.com/apache/maven-toolchains-plugin/blob/master/src/main/java/org/apache/maven/plugins/toolchain/jdk/ToolchainDiscoverer.java#L243-L250
## Code
## Problem
without arguments blocks forever until the process completes. If the
discovered JDK's java binary is:
- A script that hangs
- A broken/corrupted installation
- An interactive shell
- Extremely slow (e.g., on a network filesystem)
Maven will hang indefinitely with no way to recover other than killing the
process.
## Impact
During JDK toolchain discovery, a single problematic JDK installation can
cause the entire Maven build to hang permanently. Since discovery scans many
directories (including user-controlled paths like , , etc.), a corrupted or
slow JDK in any of these locations blocks the build.
## Suggested Fix
Use with a reasonable timeout (e.g., 30 seconds), and if the process times
out, destroy it and log a warning:
