We have seen apps to be crashing due to multiple System.load calls.
As seen from the log lines:
```
06-01 16:43:41.615 I/LSPosed-Bridge(16031): Caused by: java.lang.UnsatisfiedLinkError: Shared library "/data/app/com.example.sample-some_random_string/base.apk!/assets/lspatch/so/arm64-v8a/liblspatch.so" already opened by ClassLoader 0x1c7(dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.sample-some_random_string/base.apk"],nativeLibraryDirectories=[/data/app/com.example.sample-some_random_string/lib/arm64, /data/app/com.example.sample-some_random_string/base.apk!/lib/arm64-v8a, /system/lib64, /product/lib64]]]); can't open in ClassLoader 0x7ffc869ecc(dalvik.system.PathClassLoader[DexPathList[[zip file "/data/user/0/org.houstonmethodist.methodistmobile.debug/cache/lspatch/origin/4198609975.apk", zip file "/data/app/com.example.sample-some_random_string/base.apk"],nativeLibraryDirectories=[/data/app/com.example.sample-some_random_string/lib/arm64, /data/user/0/org.houstonmethodist.methodistmobile.debug/cache/lspatch/origin/4198609975.apk!/lib/arm64-v8a, /system/lib64, /product/lib64]]])
```
Looks like we are trying to load liblspatch.so file even when it was
loaded earlier by the ClassLoader, due to which it is causing the error.
This is similar to this issue:

Have added try ... catch block around `System.load` method to handle
exceptions / error raised from it, and have added log line to debug the
issue in cases of actual errors.
Using Map.of here results in compiler optimization generating a class
`a.a` with a method `a` that returns the Map.
The class looks like this (jadx decompilation):
```java
package a;
import java.util.AbstractMap;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
import java.util.Objects;
/* loaded from: classes.dex */
public abstract /* synthetic */ class a {
public static /* synthetic */ Map a() {
Map.Entry[] entryArr = {new AbstractMap.SimpleEntry("arm", "armeabi-v7a"), new AbstractMap.SimpleEntry("arm64", "arm64-v8a"), new AbstractMap.SimpleEntry("x86", "x86"), new AbstractMap.SimpleEntry("x86_64", "x86_64")};
HashMap hashMap = new HashMap(4);
for (int i = 0; i < 4; i++) {
Map.Entry entry = entryArr[i];
Object key = entry.getKey();
Objects.requireNonNull(key);
Object value = entry.getValue();
Objects.requireNonNull(value);
if (hashMap.put(key, value) != null) {
throw new IllegalArgumentException("duplicate key: " + key);
}
}
return Collections.unmodifiableMap(hashMap);
}
}
```
For whatever ridiculous reason, on a moto g stylus 5G (2022), when this
method is called in `LSPAppComponentFactoryStub`, the app crashes with
`java.lang.NoSuchMethodError: No static method a()Ljava/util/Map; in
class La/a; or its super classes`. Using a normal HashMap here instead
prevents this optimization from occurring, which prevents the crash.
