The gcc static analyzer reports this issue :
src/jdk.jdwp.agent/share/native/libjdwp/signature.c:49:28: warning: dereference of NULL 'tagPtr' [CWE-476] [-Wanalyzer-null-dereference] src/jdk.jdwp.agent/share/native/libjdwp/signature.c:50:12: warning: dereference of NULL 'tagPtr' [CWE-476] [-Wanalyzer-null-dereference] Normally the char *tagPtr = strchr(signature, SIGNATURE_END_ARGS); call should not return NULL; but maybe (in theory with bad/malformed input) it could happen so better add a NULL check. In debug builds, the following JDI_ASSERT should handle it. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - JDK-8392559 Changes: https://git.openjdk.org/jdk/pull/32929/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=32929&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8392559 Stats: 4 lines in 1 file changed: 3 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/32929.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/32929/head:pull/32929 PR: https://git.openjdk.org/jdk/pull/32929
