Access restriction error in Java language server log
Hi,
I have recently started using VSCode with your extension for a Gradle project, however I come across the "Access restriction" error which was flagged in other issues (#120 and #219). I have tried the proposed solution in those threads but without any luck so far.
Below are few errors that I got:
Access restriction: The type 'Signal' is not API (restriction on required library 'C:\Program Files\JAVA\openjdk11.0.5\lib\jrt-fs.jar'); code: 16777523;
Access restriction: The method 'HttpExchange.getRequestHeaders()' is not API (restriction on required library 'C:\Program Files\JAVA\openjdk11.0.5\lib\jrt-fs.jar'); code: 16777523;
And they are primarily from the below library import:
import sun.misc.Signal;
import sun.misc.SignalHandler;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
I have integrated below access rule into my build.gradle:
import org.gradle.plugins.ide.eclipse.model.AccessRule
apply plugin: 'java'
apply plugin: 'eclipse'
eclipse {
classpath {
file {
whenMerged {
def jre = entries.find { it.path.contains 'org.eclipse.jdt.launching.JRE_CONTAINER' }
jre.accessRules.add(new AccessRule('accessible', 'sun/misc/**'))
jre.accessRules.add(new AccessRule('accessible', 'com/sun/net/**'))
}
}
}
}
And the generated .classpath is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-11/">
<accessrules>
<accessrule kind="accessible" pattern="sun/misc/**"/>
<accessrule kind="accessible" pattern="com/sun/net/**"/>
</accessrules>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.buildship.core.gradleclasspathcontainer"/>
<classpathentry kind="output" path="bin/default"/>
</classpath>
It looks to me that the .classpath is ok, but somehow I am still getting the same error. The option to clean the Java language server workspace does not seem to help either. Appreciate if you can shed some lights on this.
@fbricon I afraid I cannot attach the problematic project here directly as it is not open source. I will try creating a dummy project with those library dependencies and see if I can re-produce the problem there. In the mean time, is there anything on top of your head that I should check for the problematic project? Thanks!
@fbricon I realized that there are actually some exceptions in the Java language server log file, not sure if that matters:

is there any solution to this? or what is "the right way" to solve the original problem?
@lfarkas you can try to call the 'Java: Clean the Java language server workspace' command.

thanks it's working!
There are two issues:
- one is tip says: Missing Gradle project configuration file: .settings/org.eclipse.buildship.core.prefs, cos I touch a file org.eclipse.buildship.core.prefs, and added the "org.eclipse.jdt.core.compiler.problem.forbiddenReference=ignore" to file. but it doesn't work at all.
- two issue is : Access restriction: The type 'OperatingSystemMXBean' is not API (restriction on required library '/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home/jre/lib/rt.jar')
- env:
- apple m1 pro - latest java pack - use Oracle JDK 1.8 to run the program, and use OpenJDK 17 to jdt, as the java server. - Help! It's been bothering me all day. @fbricon @snjeza @lfarkas
