@wongdh Any solution?

[aazbeltran]

I also have that problem, has anyone already found a solution?

[eduardoit2000]

i found this, and worked for me.

String pathSeparator = Syste .getProperty("path.separator");
String[] classPathEntries = System.getProperty("java.class.path") .split(pathSeparator);

Hello,
I have the same problem with jasperstarter, last version, with OPENJDK.
Unfortunately Oracle have new business policy so We need to change the JAVA JDK to OpenJDK . I tried version 8.22, version 9, version 11 and still I take this message, when I tried it to run on commandline:

OException in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

at de.cenote.jasperstarter.App.processReport(App.java:193)
at de.cenote.jasperstarter.App.main(App.java:109)

Please, Where I do the mistake? Why I can't to create the PDF file?
My apache 2.4 and PHP 7.2 running on Windows 10 saerver.

I found that the problem is with options -r
If this option is not set, the generation of the report run OK, but the problem is that subreport is not processed. If I added the option -r without any other parameter, even with path to the subreport, then the error message shows.
Please, where is the problem? Help me with it.

Thank you

I have the same problem. Even just a plain PHP file gives the following warnings when producing the .jasper file:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (file:/var/www/asa.auckland.ac.nz/pod1/app/phpjasper/bin/jasperstarter/lib/groovy-all-2.4.12.jar) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int)

WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

It does produce the file, however. But when I run the step to create the .pdf, it crashes with:

PHP version is PHP 7.2.10
JDK version is:
openjdk 11.0.2 2019-01-15 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.2+7-LTS)

I see above that eduardoit2000 says:

i found this, and worked for me.
String pathSeparator = Syste .getProperty("path.separator");
String[] classPathEntries = System.getProperty("java.class.path") .split(pathSeparator);

But I don't know what to do with these.

I have the same problem and I fixed it by installing a different jdk version and switch to it.

What JDK version are you using? can also tell how to specifically install and switch to it?

[coppolaop]

@mohamadyuzrie, Open JDK 8 fixed my problem.
I downloaded from https://jdk.java.net/java-se-ri/8-MR3 .
To switch, i just configure the build path on my eclipse IDE.

[mcjeph]

@mohamadyuzrie I was using OpedJDK version 11 & 13 when i had the problem. I fixed it using OracleJDK version 8. I don't know if higher versions will make a difference though.

Would love to try this, could you share the steps to downgrade process please? Got the package but can't figure out the command line.

Thanks in advance.
