Hi
I am using GroupDocs.Conversion to convert documents to PDF in a Spring Boot Java application.
When we run locally the JAR, everything works as expected. When we try to convert from the remote Docker container, we get the following issue:
ERROR #1
org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.groupdocs.conversion.internal.c.a.i.internal.jK.n

Configurations:
Gradle 6.4 - compile(“com.groupdocs:groupdocs-conversion:21.10”)
JAVA: openjdk 11.0.10 2021-01-19
GroupDocs Conversion: 21.10
Docker image: adoptopenjdk/openjdk11-openj9:alpine-jre
I am loading the fileBytes of a storage and returning a data stream to the microsservice, this is implementation:
InputStream in = new ByteArrayInputStream(fileBytes);
Converter converter = new Converter(in);
PdfConvertOptions options = new PdfConvertOptions();
File generatedFile = File.createTempFile(fileId, “.pdf”);
OutputStream out = new FileOutputStream(generatedFile);
converter.convert(out, options);
We intend to purchase a paid version, we only depend on the resolution of this bug to proceed with the purchase process
