Hello,

little bit of context: we have BIRT runtime integrated in our application. We updated BIRT from 2.6.2 to 4.3.2. We have notice a big slowdonw in performaces for big reports. Lots of time seems to be spent in
org.eclipse.birt.report.engine.executor.OnPageBreakLayoutPageHandle.addContent()
which seems a bug fixed for 4.6. We updated then to 4.6 but we have encounter a few problems with the dependencies, the biggest one being that all the org.eclipse.datatool.* have been compiled with java 1.8 while we are running using jdk 7, and we are getting a
Caused by: java.lang.UnsupportedClassVersionError: UnsupportedClassVersionError: Class org.eclipse.datatools.connectivity.oda.util.manifest.ManifestExplorer has unsupported major or minor version numbers, which are greater than those found in the Java Runtime Environment version 1.7.0_111

at runtime. The BIRT websiste states that the prerequisites is jdk 7, do you have any workaround to run BIRT runtime with jdk7?

Regards,
Carlo
