[BUG]: RHEL 10.2 OpenJDK update breaks Java LSP activation

Description

A recent release of patches for OpenJDK 25 on Red Hat Enterprise Linux 10.2 systems modifies the version information produced by "java -version" into a non-semver-compliant structure:

java -version
openjdk version "25.0.4.1" 2026-08-18 LTS
OpenJDK Runtime Environment (Red_Hat-25.0.4.1.1-1) (build 25.0.4.1+1-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-25.0.4.1.1-1) (build 25.0.4.1+1-LTS, mixed mode, sharing)

This breaks the version detection at https://github.com/anomalyco/opencode/blob/c2eacd72afc4a4984564c393e15ab30011057269/packages/opencode/src/lsp/server.ts#L1193

which ultimately results in an early exit of the activation function.

Possible fix:

- const m = /"(\d+)\.\d+\.\d+"/.exec(result.stderr.toString())
+ const m = /"(\d+)(?:\.\d+)*"/.exec(result.stderr.toString())

Plugins

None

OpenCode version

3. Notice that the jdtls LSP does not activate, even if already previously downloaded and installed
