The jpackage Linux launcher pipe-transfers the serialized config with a single read; with many jars it exceeds the pipe capacity, truncates, and SIGSEGVs in jvmLauncherStartJvm. Collapse app.classpath to a directory wildcard in the packaged .cfg files.

The fix looks good, but the current Linux release pipeline also uses packageReleaseDeb, packageReleaseRpm, and packageReleaseAppImage. Please make sure the classpath workaround is applied to those package paths too, not only createReleaseDistributable. |

Problem
The jpackage Linux launcher pipe-transfers the serialized application config to the JVM with a single
read. With many jars on the classpath the serialized blob exceeds the pipe capacity, gets truncated, and the packaged launcher dies with a SIGSEGV injvmLauncherStartJvm— the packaged Linux app crashes at startup.Tracked upstream as JDK-8380085.
Solution
Collapse
app.classpathin the packaged.cfgfiles to a directory wildcard (lib/app/*), shrinking the serialized config well under the pipe limit.Testing
Packaged distributable (
createDistributable) and release AppImage build and launch correctly with the flattened classpath; playback verified end to end.
