Hi devs, First, a short disclaimer, I am cross-posting this question on the calcite and on the SQuirrelSQL mailing list as I’m not really sure where the problem comes from. I am using Apache Calcite [1] as custom driver in SQuirrelSQL. Internally, Calcite uses Code generation and the Janino Compiler [2] to generate dynamic classes. Sadly, the Calcite Queries fail at this stage with the following Stacktrace: 2018-08-13 13:06:15,471 [Thread-3] DEBUG net.sourceforge.squirrel_sql.fw.util.DefaultExceptionFormatter - Error 593

Typically, you'd have 'janino.jar', or 'commons-compiler-jdk.jar', or both on the classpath. 647 at org.codehaus.commons.compiler.CompilerFactoryFactory.getDefaultCompilerFactory(CompilerFactoryFactory.java:59) 648 at org.apache.calcite.rel.metadata.JaninoRelMetadataProvider.compile(JaninoRelMetadataProvider.java:431) 649 ... 46 more I also added janino-2.76.jar as well as commons-compiler-2.7.6.jar to the classpath but the Exception does not go away. Is there any usage of these packages in SQuirrelSQL or a possibility that these are shaded or a version incompatibility exists? Thanks!
