Java version detection for JDTLS installation fails

[heoehmke]

Description

The Java version detection for JDTLS fails when java -version outputs only the major version (e.g., "21") without minor/patch numbers. The regex

opencode/packages/opencode/src/lsp/server.ts

Line 1144 in af06175

const m = /"(\d+)\.\d+\.\d+"/.exec(stderr.toString())

expects a format like "21.0.0", causing the automatic JDTLS installation to fail with the error "JDTLS requires at least Java 21" even though Java 21 is installed:

openjdk version "21" 2023-09-19 LTS
OpenJDK Runtime Environment Temurin-21+35 (build 21+35-LTS)
OpenJDK 64-Bit Server VM Temurin-21+35 (build 21+35-LTS, mixed mode)

OpenCode version

1.1.51

Steps to reproduce

1. Install Java 21 (e.g., Temurin-21+35) where java -version outputs "21" instead of "21.0.x"
2. Open a Java project with opencode
3. JDTLS fails to install with error "JDTLS requires at least Java 21"
