------------------------------------------------------------
Typically all jars on the classpath are included since we have no way to know
whether a jar is needed or not during execution.
What is the gradle configuration being used for the classpath (./gradlew
:path:to:project:dependencies)?
Which JDK version are you using? (if java11, is JPMS being enabled?)
How is the JDK being launched?
Is it a separate process?
The default is controlled by
[ClasspathScanningResourcesDetector|https://github.com/apache/beam/blob/6b472e1de8ba5769127f6c330a23cc7c0af80527/runners/core-construction-java/src/main/java/org/apache/beam/runners/core/construction/resources/ClasspathScanningResourcesDetector.java#L31]
and is configurable by this
[PipelineResourceOptions|https://github.com/apache/beam/blob/26f6dd58b9fe608476ccc33601b2e26fc0343080/runners/core-construction-java/src/main/java/org/apache/beam/runners/core/construction/resources/PipelineResourcesOptions.java#L29]
if you need to change it.
I looked at some of the jars and it looks like they aren't the JDK but some
additional deps like Nashorn (a javascript engine for the JDK)
was (Author: lcwik):
