The need for speed. What is GraalVM and how can it help you?
summary
GraalVM replaces HotSpot C2 with a Java-written JIT and adds Truffle for language implementers plus Substrate VM/native-image to produce native executables, eliminating JVM warmup (typical app startup drops from seconds to milliseconds). Key optimizations include partial escape analysis that turns heap allocations into stack/register values and Truffle AST partial evaluation for fast interpreters. Limits: native-image forbids runtime class generation and breaks many Spring runtime proxies; Community and paid Enterprise builds exist.
