Solutions

1. Fix the condition reported by the error: Command finished with exit value {} (look for stdout and stderr above): {}
2. Check the throwing call site and ensure its documented preconditions (argument values, types, environment, or configuration) are satisfied before the call.

Example fix

Validate inputs and environment so that the failing condition does not occur: Command finished with exit value {} (look for stdout and stderr above): {}

When it happens

Trigger: Thrown at compiler/src/jdk.graal.compiler.libgraal/src/jdk/graal/compiler/libgraal/GetCompilerConfig.java:160 when the library encounters an invalid state.

Common situations: Occurs when a caller violates the contract guarded by this check: Command finished with exit value {} (look for stdout and stderr above): {}
