Exec format error

[piotrblasiak]

I am building a docker image using the spring boot maven plugin with this config:

<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<image>
						<name>XXXX.amazonaws.com/${project.artifactId}:${project.version}</name>
						<buildpacks>
							<buildpack>paketo-buildpacks/java</buildpack>
							<buildpack>gcr.io/paketo-buildpacks/opentelemetry</buildpack>
						</buildpacks>
						<env>
							<BP_JVM_VERSION>${java.version}</BP_JVM_VERSION>
							<BP_ARCH>amd64</BP_ARCH>
							<BP_OPENTELEMETRY_ENABLED>true</BP_OPENTELEMETRY_ENABLED>
						</env>
					</image>
				</configuration>
			</plugin>

But when deploying it in kubernetes (m7a instances) I get:

Calculated JVM Memory Configuration: -XX:MaxDirectMemorySize=10M -Xmx2526992K -XX:MaxMetaspaceSize=378975K -XX:ReservedCodeCacheSize=240M -Xss1M (Total Memory: 3417968K, Thread Count: 250, Loaded Class Count: 64495, Headroom: 0%)
